Description

 Ether-based fuel technology

 The present invention relates to a novel clean fuel, and more particularly to a clean acid based fuel. The ether-based fuel comprises diterpene ether, ethanol and 2,6-di-tert-butyl-p-nonylphenol. More specifically, the acid-based fuel may consist of only dinonyl ether, ethanol, and 2,6-di-tert-butyl-p-nonylphenol. The invention further relates to a mixed fuel comprising the acid-based fuel of the invention and at least one other fuel selected from the group consisting of gasoline and mineral spirits. Background technique

 As a well-known, oil, as a non-renewable resource, plays an indispensable role in the social life and national defense construction of a country. With the continuous improvement of the living standards of our people, cars have gradually entered the families of ordinary people. For example, Beijing has now entered the era of 4 million cars. Therefore, as the number of cars is increasing, the need for gasoline is also increasing. China's crude oil production is far from meeting the needs of the domestic economy. Today, China has become a net importer of crude oil from crude oil exporting countries, and most of China's crude oil is dependent on imports. The intensification of this situation will seriously restrict the further development of China's economy and even affect China's national defense security. Therefore, it is necessary to find a vehicle fuel that does not require the use of petroleum raw materials, and thus does not require the import of petroleum from abroad.

 In addition, with the popularization of automobiles, a large amount of exhaust gas is discharged into the atmosphere, which makes the car bring convenience to people, and also brings various diseases, especially respiratory diseases. In recent years, automobile exhaust emissions have become the focus of attention. In order to reduce various problems caused by automobile exhaust emissions, countries around the world have imposed strict requirements on automobile exhaust, including relevant requirements in the United States, Europe has Euro IV standards, Japan has implemented the most stringent standards, and China is implementing it. Effective for Euro III or Euro IV standards. Moreover, the requirements for exhaust emissions in various countries will become more stringent. For example, the United States has agreed that states have separately set stricter emission standards than US national standards. On the eve of the Olympic Games, Beijing implemented the National IV standard in advance and will implement the National V standard as soon as possible. Therefore, there is a need for a clean fuel that can replace the currently used motor gasoline, which is more clean and environmentally friendly while meeting the functions of the motor gasoline.

 Benzene is a recognized carcinogen. It is directly affected by the evaporation and combustion of gasoline and the release of exhaust gas into the atmosphere. Therefore, the indicator is restricted in the EU, UK, Australia and Russia gasoline standards, generally not more than 5% (v/v). According to Beijing local standards, the content of benzene is required to be no more than 1.0% by volume. However, as environmental requirements, governments and relevant agencies may also impose more stringent restrictions.

An aromatic hydrocarbon is a gasoline blending agent with a high octane number and a high calorific value. However, it burns to cause the formation of carcinogen benzene, and it is easy to increase the carbon deposit of the combustion chamber and increase the emission of C0 ₂ . Generally think of steam The greater the content of benzene and other aromatics in the oil, the greater the benzene content of the combustion products. Therefore, reducing the aromatics content in gasoline is bound to benefit the environment by reducing benzene emissions from the tail gas.

 China is a large coal producing country with abundant coal reserves. Converting rich coal resources into fuel oil has always been a research direction. Converting coal into ethanol, diterpene ether is also an important direction for coal utilization. Shaanxi New Fuel Burner Company and other units have developed acid-based gasoline additives containing 5 - 37 % diammonium ether, 10 - 60 % low-carbon alcohol compounds, and 10 - 50% C5-10 hydrocarbons. Compound, 0.1 - 5% alkylphenol to polyoxyethylene ether and 0.05 - 0.5% alkylphenol. The additive is mixed with gasoline to produce an acid-based compound gasoline. Chinese invention patent application CN98112948.X also discloses an acid-based gasoline additive consisting of the following components: 15.5% diterpene ether, 42% decyl alcohol, 39% benzene, 3.3% alkylphenol ethoxylate and 0.2 %2,6-di-tert-butyl-p-phenol. Affected by this, the annual production of diterpene ether in China can now reach several million tons. However, the above two ether-based gasoline additives have high production costs and contain a large amount of benzene, so that the gasoline added with these two acid-based gasoline additives will not meet the requirements of the current gasoline standard for benzene content. Moreover, it is believed that the addition of benzene to gasoline will inevitably lead to a sharp increase in the benzene content of the gasoline combustion products, thereby causing damage to the environment and the human body. Nowadays, many diterpene ether producers are in a limited production or stop production due to product sales problems, waiting for a difficult situation.

 Therefore, if diterpene ether can be used to produce clean fuels, there is no need to worry about the source of raw materials, and it will solve the current problems of these manufacturers.

 Although the standard of sterol gasoline has been promulgated, due to the material properties of sterol, there are still some problems in sterol gasoline: First, the volatility of sterols relative to gasoline components is poor, resulting in difficulty in cold start of engines using sterol gasoline. Insufficient combustion; Second, the miscibility of sterols with gasoline is poor, the shelf life is short, and it is easy to deteriorate and stratify; the third is that the substitution ratio is low (that is, about 1.6-1.7 parts of sterol need to be used instead of 1 part of gasoline); Engine structure, sterol gasoline is not fully burned in existing engines, and its power is insufficient.

 Ethanol gasoline has been used in some parts of China. However, ethanol gasoline also has some problems, such as easy moisture absorption, short shelf life due to moisture layer, low substitution ratio and insufficient power.

 The additives used in oils such as gasoline and diesel mainly include the following: 1) antiknock agents, which are used to improve the combustion characteristics of gasoline and increase its octane number; 2) antioxidants, which are used to improve the inclusion of secondary Oxidation stability of processed components of gasoline and diesel; 3) Antifreeze, used to prevent trace water in jet fuel from forming at low temperature, resulting in engine normal operation due to difficulty in oil transportation; 4) Antistatic agent, used for Improve the conductivity of oils such as jet fuel to prevent fires caused by frictional electricity during high-speed pump delivery and filtration; and 5) Fluidity improvers for changing the crystal shape of paraffin in diesel to improve oil at low temperatures Mobility, and so on.

Tert-butanol (TBA) has good solubility and is generally used as a cosolvent for sterols to increase the octane number of gasoline. In the prior art, t-butanol has not been added to an acid-based fuel containing ethanol. Improve octane number, improve combustion performance and alleviate ethanol moisture absorption.

 The inventors of the present invention have undergone extensive testing and screening, and it has unexpectedly been found that a novel fuel comprising didecyl ether, ethanol and 2,6-di-tert-butyl-p-nonylphenol can be used to solve or partially overcome the above problems in the art. .

 First aspect of the invention

 A first aspect of the invention relates to a novel acid-based fuel which is a dioxane-based fuel. Specifically, the novel fuel comprises diterpene ether, ethanol, and 2,6-di-tert-butyl-p-nonylphenol.

The novel acid-based fuel of the present invention does not use petroleum resources, and can completely replace petroleum-derived gasoline as a fuel for the automobile industry, and can also use ethanol derived from crops as a main component. Heretofore, it has not been anticipated from the prior art that a composition comprising didecyl ether, ethanol and 2,6-di-tert-butyl-p-nonylphenol as a main component can be used as a fuel, particularly as a fuel for vehicles. Instead of gasoline. Unpredictable by diterpene ether, ethanol and 2,6-di uncle

κ , ,

 Gasoline is usually a mixture of C4-C10 alkanes and contains benzene and toluene, aromatics and olefins.

In this article, "gasoline" includes regular gasoline, sterol gasoline and ethanol gasoline.

 The acid-based fuel of the present invention does not contain a main component of gasoline, i.e., the acid-based fuel of the present invention does not contain a hydrocarbon of C4 or higher, such as a C4-C10 alkane, benzene or the like. As used herein, "does not contain hydrocarbons above C4" means that no hydrocarbons above C4 are intentionally added.

 The acid-based fuel of the present invention mainly comprises didecyl ether, ethanol and 2,6-di-tert-butyl-p-nonylphenol. In general, in the acid-based fuel of the present invention, the content of the diterpene ether may be 4 to 15 parts by weight, and the content of the ethanol may be 85 to 96 parts by weight, and the content of 2,6-di-tert-butyl-p-nonylphenol The content is 0.005 to 0.5 part by weight, and the total weight of dioxane and ethanol is 100 parts by weight. Preferably, in the acid-based fuel, the content of diterpene ether is 8-15 parts by weight, the content of ethanol is 85-92 parts by weight, and the content of 2,6-di-tert-butyl-p-nonylphenol is 0.008-0.02 weight. Parts, wherein the total weight of dioxane and ethanol is 100 parts by weight. More preferably, in the acid-based fuel, the content of the diterpene ether is 10-15 parts by weight, the content of ethanol is 85-90 parts by weight, and the content of 2,6-di-tert-butyl-p-nonylphenol is 0.009-0.012. Parts by weight, wherein the total weight of dioxane and ethanol is 100 parts by weight.

 These three components are described in detail below.

Dimethyl ether is a colorless, odorless and non-toxic compound. Dioxin is a gas at normal temperature and pressure. Its molecular weight is 46, oxygen content is 35, air-fuel ratio is 9, air-fuel mixture is higher than diesel (3067/2911), cetane number is 60 (5-12 units higher than diesel), exhaust emissions Medium CO and HC are 55% and 86% lower than gasoline, respectively. Therefore, the combustion of diterpene ether is more complete than that of gasoline, and the combustion products are more environmentally friendly than gasoline. The diterpene ether has good combustion and mechanical properties and strong explosive power, and these properties are superior to those of mercapto tert-butyl ether. Ethanol in this application refers to anhydrous ethanol, which has a high oxygen content (about 35%) and a large octane number (ethanol octane number is 111, 14-21 units higher than gasoline), and pollutant emissions are better than gasoline. . Ethanol has a wide range of sources, especially from cassava, straw, and especially corn, by fermentation, at a lower cost. In China, since ethanol gasoline has been used, the supply of ethanol, especially ethanol for fuel, has not become a problem.

 The diterpene ether used in the present invention can be derived from a coal-based polygeneration, that is, a recycled material for recycling and recycling of a fertilizer plant, which has a wide range of sources and low cost.

The molecular weight of 2,6-di-tert-butyl-p-phenol (CAS No. 128-37-0, molecular formula C ₁₅ H ₂₄ 0 ) is 220, and its structural formula is as follows:

/ . 2,6-di-tert-butyl-p-phenol is white crystal, which turns yellow when it is light, and gradually becomes darker. It is soluble in benzene, toluene, decyl alcohol, acetophenone, ethanol, isopropanol, petroleum ether, linseed oil, insoluble in water and 10 °C caustic soda solution. 2,6-di-tert-butyl-p-phenol is commercially available.

 The acid-based fuel of the present invention has the advantages of high clean combustion (and thus high clean emissions) of dioxane and the high octane value of ethanol. Therefore, the acid-based fuel can have a high octane number, and is fully burned and discharged. Low pollution, easy access to raw materials and low cost. The acid-based fuel of the present invention can meet the requirements of the automobile industry for gasoline, thereby replacing the conventional gasoline as a fuel for automobiles.

 More particularly, the acid-based fuels of the present invention are also self-cleaning. Without wishing to be bound by a particular theory, the inventors of the present invention believe that since ethanol has good solubility properties, it can effectively prevent carbon deposits from forming in spark plugs, combustion chambers, valves, exhaust pipe muffler, etc., preventing oil blockage and avoiding Self-cleaning occurs due to failure caused by carbon deposits and clogging. Surprisingly, the ether-based fuel of the present invention can accomplish this self-cleaning function without the addition of any other additives.

 The effect of adjusting the octane number can be achieved by adjusting the content of dimethyl ether and ethanol in the acid-based fuel. In general, as the content of ethanol decreases, the octane number of the acid-based fuel of the present invention also decreases. However, since the octane number of ethanol itself is very high, the acid-based fuel of the present invention has a relatively high octane number without using an octane number improver.

The inventors of the present invention have, after extensive research work, unexpectedly discovered that the acid-based fuel of the present invention containing a specific proportion of dinonyl ether, ethanol and 2,6-di-tert-butyl-p-nonylphenol does not contain gasoline. The main component, particularly a hydrocarbon of C4 or higher, such as benzene, can be used as an automobile fuel, and has a remarkably low colloid content and a significantly long shelf life and induction period. Further, since the acid-based fuel of the present invention can be directly used as an automobile fuel without containing a hydrocarbon such as benzene or the like, such as benzene, it is possible to satisfactorily meet environmental protection requirements. 2,6-di-tert-butyl-p-phenol The content is preferably 0.005 to 0.5 part by weight, preferably 0.008 to 0.02 part by weight, more preferably 0.009 to 0.012 part by weight based on 100 parts by total of the total amount of dioxane and ethanol.

 When the content of diterpene ether, ethanol and 2,6-di-tert-butyl-p-nonylphenol is within the above range, the acid-based fuel of the present invention has a good effect. The acid-based fuel of the present invention has the advantages of high clean combustion (and thus high clean emissions) of dioxane as described above, as well as the high octane value of ethanol and the self-cleaning characteristics, as well as a significantly low gel. Quality and significantly long shelf life and induction period.

 The ether-based fuel of the present invention may be used without any other additives, that is, the ether-based fuel of the present invention may consist of only dinonyl ether, ethanol and 2,6-di-tert-butyl-p-nonylphenol. However, other components or additives may be added depending on the needs of the particular application to further improve certain properties of the resulting fuel.

 Since the novel acid-based fuel of the present invention is different from conventional fuels such as gasoline and diesel, conventional gasoline additives are not necessarily usable for the acid-based fuel of the present invention. Before the conventional additives are used in the acid-based fuel of the present invention, the compatibility test must first be carried out. The compatibility test herein means that the additive to be used can be dissolved in the acid-based fuel of the present invention and can be stably present without changing the properties of the acid-based fuel of the present invention. Only those additives which are compatible with the acid-based fuel of the present invention are likely to be used in the acid-based fuel of the present invention. In addition, it is also noted that the addition of additives does not affect the unique properties of the acid-based fuels of the present invention.

 Conventional gasoline additives which may be used in the acid-based fuel of the present invention include, for example, catalysts, oxidizers, antioxidants, combustion improvers, detergents and the like. These additives may be added to the ether-based fuel of the present invention after passing the compatibility test, provided that the unique properties of the acid-based fuel of the present invention are not significantly adversely affected. It is also possible to add a combination of additives to the acid-based fuel of the present invention, provided that the unique properties of the acid-based fuel of the present invention are not significantly adversely affected.

 The inventors have found through extensive experiments that some commercially available additive products are acid-based fuels that can be used in the present invention, such as ethanol gasoline detergents produced by the Petrochemical Research Institute, and fuel-saving fuels produced by Henan Xinxiang Si Te Fuel Saver Factory. Detergents, catalysts, oxidizers, antioxidants, combustion improvers, metal passivators, corrosion inhibitors, water repellents, anti-corrosion agents, smoke suppressants, etc., which are compatible with this acid-based fuel. product.

The method for preparing the acid-based fuel of the present invention is not particularly limited, and the ether-based fuel of the present invention can be obtained by a conventional technique in the chemical industry. The preparation of the ether-based fuel of the present invention comprises the addition of 2,6-di-tert-butyl-p-nonylphenol and optionally other additives, as well as the mixing of dioxane and ethanol. In general, 2,6-di-tert-butyl-p-phenol and optionally other additives can be added to the ethanol and then mixed with the dioxane. However, it is also possible to first carry out the mixing of dioxane and ethanol, followed by the addition of 2,6-di-tert-butyl-p-nonylphenol and optionally other additives. For post-addition of additives, if agitation is required, it should be stirred slowly. For the mixing of dioxane and ethanol, it is usually possible to use gas to absorb The mixing of body and gas is a conventional technique in the chemical industry. The ether-based fuel of the present invention is obtained by a method of physical absorption, and relates only to the absorption of dinonyl ether by ethanol. In general, countercurrent absorption is typically selected to accomplish the preparation of the acid based fuels of the present invention. The invention has no limitation on the selection of the absorption tower, and a packed tower or a plate tower can be selected. The present invention also has no limitation on the absorption conditions. When the chemical engineering technician faces the specific purpose of the absorption of dioxane gas by ethanol, the absorption tower and the absorption conditions are selected according to the basic chemical principle and the relative content required. . In general, absorption of dioxins by ethanol can be accomplished by conventional ambient temperature absorption.

 This absorption process can be briefly described as follows: The diterpene ether gas is passed from the bottom of the absorption tower through a metering device (such as a gas distributor); at the same time, the ethanol is (or pre-mixed with 2,6-di-tert-butyl pair). The indophenol and optionally other additives are added from the top of the column, and the gas-liquid two phases flow countercurrently in the absorption column and are in direct and sufficient contact so that the dioxane gas is absorbed by the ethanol. Depending on the choice of absorption column and its efficiency, one-way absorption or cyclic absorption can be used. For cyclic absorption, the diterpene ether-containing ethanol from the bottom of the column (and optionally containing 2,6-di-tert-butyl-p-nonylphenol and optionally other additives) can be re-conveyed back to the top of the column and Introduced into the column, the gas from the top of the column is re-conveyed back to the bottom of the column and introduced into the column, thereby repeating the absorption process of the dioxane gas. This repeated absorption can be performed as many times as needed. However, it will also be apparent to those skilled in the art that the diterpene ether can be substantially dissolved in ethanol by one-way absorption of the absorption column to achieve the desired diterpenic acid content without repeated absorption.

 The stability of the acid-based fuel of the present invention is much higher than that of ordinary gasoline. This can be confirmed from the induction period and the gel content after the acid-based fuel of the present invention is stored for a long period of time.

 The inventors of the present invention have found that the ether-based fuel of the present invention has the advantages of high oxygen content, low vapor pressure, low sulfur, low benzene, low aromatics and no lead. The acid-based fuel of the present invention can be used in existing vehicles without changing the engine structure. Second aspect of the invention

 The additives are described in detail below.

The succinimide (CAS: 123-56-8) has a molecular formula of C ₄ 3⁄4N0 ₂ and a molecular weight of 99.09, also known as succinimide, 2,5-pyrrolinedione, succinic acid diimide, etc. , its structural formula is as follows:

Soluble in water, alcohol or sodium hydroxide solution, insoluble in ether and chloroform. Sweet. this invention The succinimide used can be a commercial product sigma produced by any process such as chlorination, thermal addition.

It is a colorless volatile liquid in the presence of a small amount of water. It has a camphor-like odor, is hygroscopic, and is flammable. The melting point of tert-butanol is 25.55. C, a boiling point of 82.5 ° C, a relative density of 0.7867. Tert-butanol is soluble in most organic solvents such as alcohols, esters, ketones, aromatics and aliphatic hydrocarbons. These properties make tert-butyl alcohol a useful solvent and additive and are one of the most widely used chemical products. The tert-butanol used in the present invention may be a commercial product produced by any process such as isobutylene indirect hydration, isobutylene direct hydration, and isobutane/propylene co-oxidation to produce propylene oxide co-produced t-butanol.

 Similarly, the inventors of the present invention unexpectedly found that the diterpene ether, ethanol, 2,6-di-tert-butyl-p-nonylphenol, and the at least one selected from the group consisting of t-butanol and succinimide The acid-based fuel of the additive can be used as an automobile fuel without containing the main component of gasoline, especially a hydrocarbon such as benzene, such as benzene, and has a significantly low colloid content and a remarkable long shelf life. And induction period. Further, since the acid-based fuel can be directly used as an automobile fuel without containing a hydrocarbon such as benzene or the like, such as benzene, it is possible to satisfactorily meet environmental protection requirements.

 The acid-based fuel of the present invention mainly comprises didecyl ether, ethanol, 2,6-di-tert-butyl-p-nonylphenol, and the at least one additive selected from the group consisting of t-butanol and succinimide. In general, in the acid-based fuel of the present invention, the content of the diterpene ether may be 4 to 15 parts by weight, and the content of the ethanol may be 85 to 96 parts by weight, and the content of 2,6-di-tert-butyl-p-nonylphenol The content is 0.005 to 0.5 part by weight, and the total weight of dioxane and ethanol is 100 parts by weight. Preferably, in the acid-based fuel, the content of the diterpene ether is 8-15 parts by weight, the content of ethanol is 85-92 parts by weight, and the content of 2,6-di-tert-butyl-p-nonylphenol is 0.008-0.02 weight. Parts, wherein the total weight of dioxane and ethanol is 100 parts by weight. More preferably, in the acid-based fuel, the content of the diterpene ether is 10-15 parts by weight, the content of ethanol is 85-90 parts by weight, and the content of 2,6-di-tert-butyl-p-nonylphenol is 0.009-0.012. Parts by weight, wherein the total weight of dioxane and ethanol is 100 parts by weight.

 Although the acid-based fuel of the present invention has a self-cleaning effect, since the fuel itself has impurities, the rust is mixed in the production, transportation, and storage, and the unstable components in the fuel are easily reacted, so that sediments are easily formed, resulting in The idle speed is unstable, the acceleration is deteriorated, the fuel consumption is increased, and the emission of harmful gases such as hydrocarbons, carbon monoxide and nitrides is increased. To further enhance the cleaning action of the acid-based fuel of the present invention, further increase the cleaning of the oil passage system and reduce the generation of engine carbon deposits, the ether-based fuel of the present invention may further contain a detergent.

The inventors have found that the acid-based fuel of the present invention containing didecyl ether, ethanol and 2,6-di-tert-butyl-p-nonylphenol preferably further contains a detergent succinimide as an additive. The succinimide contains a polar region and a non-polar region, and its polar region surrounds the tiny particles of the formed deposit to form micelles, which are dispersed into the fuel for cleaning purposes; Adsorbed on a metal or ion surface to form A layer of molecular protective film prevents the deposition of particles or adheres to the metal surface to maintain cleanliness. Therefore, succinimide can remove sludge and carbon deposits from the carburetor and crankcase system, reduce atmospheric pollution, reduce CO emissions, reduce HC (hydrocarbon) emissions, and reduce oil pumps. And the wear of the injector prevents the cremation plug from coking and increases the power of the engine, thereby saving energy and improving fuel economy.

 To date, in the field of gasoline additives, it has been suggested that succinimide cannot be effectively cleaned in a small amount due to insufficient thermal stability. However, the inventors of the present invention unexpectedly have found that a lower level of succinimide can be used in the acid-based fuel of the present invention, and the cleaning effect of the acid-based fuel of the present invention can be effectively improved. While not intending to be bound by a particular theory, the inventors of the present invention believe that the reason why a small amount of succinimide can function in the present invention can be explained as follows: First, unlike the exothermic reaction of conventional gasoline, The combustion of the acid-based fuel of the invention is an endothermic reaction. Therefore, when the acid-based fuel of the present invention is burned, the temperature in the engine is lower than the temperature at which the gasoline is burned, which lowers the decomposition of the succinimide. Second, since conventional fuels such as diesel and gasoline do not have a detergency effect, when succinimide is used in diesel and gasoline, a larger amount of succinimide is required to be used. The detergency caused by pyrolysis of the amine is reduced. However, in the acid-based fuel of the present invention, since the acid-based fuel of the present invention itself has a self-cleaning action when it does not contain succinimide as described above, the effective amount of succinimide is required. Smaller. Therefore, even if the effective content of the succinimide is lowered due to the high temperature condition of the engine, the detergency of the succinimide in the acid-based fuel of the present invention is not affected.

 In the acid-based fuel of the present invention, when it contains succinimide, the content of the succinimide may be 0.005 - 0.02 parts by weight based on 100 parts by weight of the total weight of the dinonyl ether and the decyl alcohol. Preferably, the content of the succinimide is from 0.006 to 0.015 parts by weight, and more preferably the content of the succinimide is from 0.008 to 0.012 parts by weight.

 Therefore, the acid-based fuel of the present invention can achieve clean combustion, clean emissions, and protect the vehicle.

 The inventors of the present invention have found that the acid-based fuel of the present invention containing didecyl ether, ethanol and 2,6-di-tert-butyl-p-nonylphenol further enhances the function of the acid-based fuel when t-butanol is contained as an additive. effect. In acid-based fuels, t-butanol acts to increase octane number, improve combustion performance, and mitigate ethanol moisture absorption. In prior art gasoline, tert-butyl alcohol is used in large quantities as an additive to gasoline to increase the octane number of gasoline. In the acid-based fuel of the present application, tert-butanol not only exerts its function of improving octane number and improving combustion performance, but also can be dissolved in any ratio with water to form a constant boiling mixture with water, thereby alleviating ethanol moisture absorption. Sexuality, and solve the problem of gas resistance in the use of alcohol fuels. The tert-butyl alcohol is preferably contained in an amount of from 0.5 to 2 parts by weight, preferably from 0.7 to 1.5 parts by weight, more preferably from 0.8 to 1.2 parts by weight, most preferably from 0.9 to 1.1 parts by weight, based on 100 parts by total of the total amount of dimethyl ether and ethanol.

 The acid-based fuel of the present invention may be used without any other additives. However, other components or other additives may be added depending on the needs of the particular application to further improve certain properties of the resulting fuel.

Since the novel acid-based fuel of the present invention is different from conventional fuels such as gasoline and diesel, conventional gasoline additives are not necessarily usable for the acid-based fuel of the present invention. Before the conventional additives are used in the acid-based fuel of the present invention, the compatibility test must first be carried out. The compatibility test herein means that the additive to be used can be dissolved in the acid-based fuel of the present invention and can be stably present without changing the properties of the acid-based fuel of the present invention.

However, it is also possible to first carry out the mixing of diterpene ether and ethanol, and then add 2,6-di-tert-butyl-p-nonylphenol, at least one additive selected from t-butanol and succinimide, and optionally other additives. . For post-addition of additives, if agitation is required, it should be stirred slowly. For the mixing of diterpene ether and ethanol, it is common to use a gas absorption tower for mixing. The 'ether-based fuel of the present invention is obtained by a method of hydrazine absorption, and only relates to the absorption of diterpene ether by ethanol. In general, countercurrent absorption is typically selected to accomplish the preparation of the acid based fuels of the present invention. The invention does not have any limitation on the selection of the absorption tower, and a packed tower or a tray tower can be selected. The present invention also has no limitation on the absorption conditions. When the chemical engineering technician faces the specific purpose of the absorption of dioxane gas by ethanol, the absorption tower and the absorption conditions are selected according to the basic chemical principle and the relative content required. . In general, absorption of dioxins by ethanol is accomplished by absorption at room temperature.

This absorption process can be briefly described as follows: The diterpene ether gas is passed from the bottom of the absorption tower through a metering device (such as a gas distributor); at the same time, the ethanol is (or pre-mixed with 2,6-di-tert-butyl pair). The indophenol, at least one of the additives selected from the group consisting of t-butanol and succinimide, and optionally other additives, are added overhead, and the gas-liquid two phases flow countercurrently within the absorption column and are directly and sufficiently contacted such that Dioxin gas is absorbed by ethanol. Depending on the choice of absorption tower and its efficiency, one-way absorption or cyclic absorption can be used. For cyclic absorption, it can be included from the bottom of the tower. Ethanol with dimethyl ether (and optionally 2,6-di-tert-butyl-p-phenol, at least one additive selected from t-butanol and succinimide, and optionally other additives) is re-delivered back The top of the column is introduced into the column, and the gas from the top of the column is re-conveyed back to the bottom of the column and introduced into the column, thereby repeating the absorption process of dioxane gas. This repeated absorption can be performed as many times as needed. However, it will also be apparent to those skilled in the art that the diterpene ether can be substantially dissolved in ethanol by one-way absorption of the absorption column to achieve the desired diterpenic acid content without repeated absorption.

 The stability of the acid-based fuel of the present invention is much higher than that of ordinary gasoline. This can be confirmed from the induction period and the gel content after the acid-based fuel of the present invention is stored for a long period of time.

The acid-based fuel of the present invention can be used in existing vehicles without changing the engine structure. Third aspect of the invention

 In a third aspect of the invention, the invention relates to a mixed fuel comprising at least one of the acid-based fuel of the first or second aspect of the invention and other fuels, such as gasoline and solvent oil No. 180. Ben

'The following is a description of the case where it burns the gasoline '^o solvent oil and the combination.

 Other fuel is gasoline

The inventors have found that the acid-based fuel of the present invention can be used alone as a fuel for engines, particularly gasoline engines. Therefore, the acid-based fuel of the present invention can completely replace gasoline for automobile fuel. However, it is also possible to use the acid-based fuel of the present invention with conventionally used gasoline, or sterol gasoline or the mixed fuel of the present invention, which may comprise a fuel and a gasoline on the one hand: ' ^: ", in the present invention When the ether-based fuel is mixed with gasoline, the mixing ratio of the ether-based fuel of the present invention and gasoline can be arbitrarily adjusted as needed.

 In general, in the gasoline-containing mixed fuel of the third aspect of the invention, the acid-based fuel of the first or second aspect of the invention may be contained in an amount of from 1 to 99% by weight based on the total mass of the mixed fuel. Preferably, the acid-based fuel of the first or second aspect of the invention may be contained in an amount of from 10 to 90% by weight, more preferably from 30 to 70% by weight, based on the total mass of the mixed fuel. Preferably, the content of gasoline is correspondingly from 90 to 10% by weight, more preferably from 70 to 30% by weight.

In the present application, ordinary gasoline means gasoline which is not added with dioxane, decyl alcohol or ethanol. The sterol gasoline and the ethanol gasoline respectively refer to gasoline to which sterol or ethanol is added. Since the ethanol has been added to the ethanol gasoline, when the acid-based fuel of the present invention is mixed with the ethanol gasoline, the ethanol gasoline has The ethanol will change the diterpene ether to ethanol ratio of the acid-based fuel of the present invention. Therefore, when the ether-based fuel of the present invention is used in combination with ethanol gasoline, depending on the specific conditions and uses, it is necessary to consider the ethanol content in the ethanol gasoline to finally determine the mixing ratio of the acid-based fuel of the present invention and the ethanol gasoline. Alternatively, when the acid-based fuel of the present invention is used in combination with ethanol gasoline, depending on the specific conditions and uses, it is necessary to consider the ethanol content in the ethanol gasoline to ensure that the introduction of ethanol in the ethanol gasoline does not result in the acid-based fuel of the present invention. The content ratio of the diterpene ether and ethanol deviates from the scope of the present invention. In general, in order to make the dibasic acid content of the acid-based fuel of the present invention within a preferred range of 4 - 15 (for example 5 - 10 ) parts by weight (calculated as the total amount of 100 parts by weight of ethanol and dioxane), In the case of ethanol gasoline, the mixing ratio of ethanol gasoline should not exceed 50%. For example, ethanol gasoline contains 10% by weight of ethanol. When mixing, the ratio of diether ether used should be considered. To ensure the fuel performance of the mixed fuel after mixing, the mixing ratio of ethanol gasoline should not exceed 50% of the ether-based fuel of the present invention. .

More preferably, the acid-based fuel of the present invention is compounded with ordinary gasoline in a weight ratio of 20:80 to 80:20. More preferably, the acid-based fuel of the present invention is compounded with ordinary gasoline in a weight ratio of 30:70 to 70:30.

 When the mixing ratio of the acid-based fuel is as high as 80%, that is, 80 parts by weight of the acid-based fuel of the present invention is mixed with 20 parts by weight of ordinary gasoline (for example, No. 90 gasoline), the obtained mixed fuel is stable in quality and can be stored at room temperature. 1 year does not stratify.

 There is no particular limitation on the method of obtaining a mixed fuel containing gasoline. The mixed fuel can be obtained by mixing the ether-based fuel of the present invention with gasoline. For example, the ether-based fuel of the present invention may be added to gasoline, or gasoline may be added to the acid-based fuel of the present invention, or the ether-based fuel of the present invention and gasoline may be simultaneously added to a separate container and uniformly mixed. To get a blend of fuel. Slow agitation can be used to promote mixing.

 As described above, since the acid-based fuel of the present invention has a high octane number, usually more than 100, the acid-based fuel of the present invention can be used to increase the number of ordinary gasoline. For example, the acid-based fuel of the present invention can be used to make the No. 90 or No. 93 gasoline reach the standard of No. 93 or No. 97 gasoline, respectively.

 Further, the use of the acid-based fuel of the present invention can also improve the stability of ordinary gasoline. In general, the stability of commercially available regular gasoline is not good enough. By blending the acid-based fuel of the present invention with commercially available ordinary gasoline, the induction period of ordinary gasoline can be increased and the gum content can be lowered.

When the acid-based fuel of the present invention is mixed with normal gasoline in a ratio of 30% or in a ratio of 20% with methanol or ethanol gasoline, the power and fuel saving effect can be achieved. Under the same operating conditions of the engine, the fuel saving ratio can be as high as 10% or more. Use The acid-based fuel of the present invention is compounded with gasoline, and the substitution ratio can be increased to 0.7 to 1 (the substitution ratio of ethanol gasoline is 1.6-1.7). Here, the substitution ratio refers to the weight fraction of ethanol gasoline or the ether-based fuel of the present invention which is required to replace one ordinary gasoline. Further, by using the ether-based fuel of the present invention, the exhaust gas emission can be greatly reduced, thereby providing an excellent environmental effect.

However, since the octane number of the solvent oil No. 180 is low, at this time, it is preferable that the content of the solvent oil No. 180 is not more than 20% by weight based on the total weight of the mixed fuel.

 There is no particular limitation on the method of obtaining a mixed fuel comprising a combination of gasoline and No. 180 solvent oil and the acid-based fuel of the present invention. The mixed fuel can be obtained by mixing the acid-based fuel of the present invention with gasoline and solvent oil No. 180. For example, the ether-based fuel of the present invention and gasoline and solvent oil No. 180 can be added to separate containers and mixed uniformly to obtain a mixed fuel. Slow agitation can be used to promote mixing. The invention will now be further described by way of specific examples. However, the invention is not limited by these specific examples.
