Description
Technical field
The present invention relates to liquid fuel, more particularly, be a kind of be the vehicle ethanol fuel of main raw material preparation with ethanol and lighter hydrocarbons.
Background technology
From seventies in 20th century for the second time behind the world oil crisis, the research work of methanol gasoline and ethanol petrol all seeking alternative fuel, is carried out in countries in the world.China is along with economy develops fast, and oil consumption increases sharply with the speed in year 13%, and China's net importation oil had reached 4,000 ten thousand tons in 1999, will break through 100,000,000 tons this year.In recent years, the demand of China's refined oil had the rate of increase of scholarly forecast gasoline in 2005 to reach 4.4%, the gasoline consumption reaches 4,300 ten thousand tons, and the increase of automobile amount, make atmospheric pollution even more serious, the clean fuel surrogate of therefore seeking environment-friendly type has become trend of the times.China once carried out methanol gasoline and automotive research exploitation thereof in " six or five ", the enforcement period of the seventh five-year plan, at present some technology is existing breaks through (as number of patent application: 02104311.6, a kind of production technique of ethanol petrol), but some difficult point is also treated further solution, therefore do not obtain practical application (contemporary petrochemical complex as yet, 2003,11 (6): 6-8).
Summary of the invention
The purpose of this invention is to provide that a kind of dynamic performance is good, cost is low, calorific value is high, pollute the ethanol clean fuel of circlet guarantor type.
Main technical schemes of the present invention: ethanol is joined in the lighter hydrocarbons, be aided with fuel dope again, be mixed with required fuel.
The composition of fuel of the present invention and weight percentage thereof:
Ethanol 15-35%, lighter hydrocarbons 20-40%, 1
#Coal tar 10-20%, 6
#Solvent oil 15-35%, trimethyl carbinol 3-5%, combustion improver 02-1.0%, detergent-dispersant additive 0.03-0.08%, anticorrosion inhibitor 0.05-0.1%, metal passivator 0.01-0.06%.
Described lighter hydrocarbons, its fraction scope is 30-205 ℃, is to analyse oil by separating facing of obtaining in the Sweet natural gas of oil field.
Described 1
#Coal tar, its fraction scope is 30-200 ℃, is provided by Harbin Gas Works.
Described 6
#Solvent oil, its fraction scope is 60-90 ℃, is the production of grand celebration Fine Chemical Works.
The described trimethyl carbinol is a solubility promoter, is that rubber plant of Qilu Petroleum Chemical Corporation Institute produces.
Described combustion improver is to be formed by ether, acetone and hydrogen peroxide allotment, and its volumetric mixture ratio is 1: 1: 1.
Described detergent-dispersant additive, its trade mark are T151, the chemical name mono butonediimide, and Lanzhou general petrochemicals factory produces.
Described anticorrosion inhibitor, its trade mark are BR-7903, and chemical name is a fatty acid ester, and petrochemical complex institute in Beijing's provides.
Described metal passivator, its trade mark are T1201, and chemical name is N, N '-two inferior bigcatkin willow-1, and the 2-propylene diamine, Jinzhou Petrochemical Co. produces.
Fuel compound method of the present invention: at normal temperatures and pressures, earlier with lighter hydrocarbons and 1
#Coal tar joins in the container, and mixing adds ethanol, 6 again
#Solvent oil, the trimethyl carbinol, combustion improver, detergent-dispersant additive, anticorrosion inhibitor and metal passivator, mixing promptly gets required fuel.
Advantage of the present invention and effect:
(1) ethanol in the fuel of the present invention is a kind of energy, is again a kind of good gasoline quality improving agent, and it can improve the octane value of gasoline, and peace and quiet engine reduces the objectionable impurities in the vehicle exhaust effectively.Show through engine rig test and row test-results, use this engine fuel need not transform, dynamic performance is constant substantially, and exhaust emissions amount CO and CH compound decreased average are more than 30%, oil consumption slightly reduces, but because of containing oxygen in the ethanol, make the gasoline oxygen level increase by 4%, part that can not perfect combustion in the gasoline fully can be burnt, CO reduces by 33% in the tail gas, thereby make the corresponding minimizing of oil consumption, both offset, and overall oil consumption are maintained an equal level or slightly decline.
(2) fuel of the present invention can use separately, also can join non-lead gasoline for car with any ratio and mix use.
(3) preparation method of the present invention is simple, can prepare in non-pressure vessel, so low cost of manufacture, produces, accumulating is very convenient.
(4) fuel element wide material sources of the present invention, described ethanol can make from agricultural-food such as corn, wheat.China is large agricultural country, and the comprehensive productivity of grain is near 500,000,000 tons, can solve the transition problem of farm crop such as grain so effectively, and helping increases and stable farmers' income.
(5) therefore fuel of the present invention do not have corrosion to metal owing to be added with anticorrosion inhibitor; Most elastomeric materials there is not the swelling phenomenon; Fuel of the present invention in addition even if under-45 ℃ low temperature, demixing phenomenon can not occur in 1 year under air-proof condition.
In sum, fuel production of the present invention is simple, low cost of manufacture, and raw material sources are extensive, and the more important thing is and reduced objectionable impurities in the discharging tail gas, be the wide environment-friendly type clean fuels of a kind of market outlook therefore.
