Description

 Methanol gasoline core mother liquor and methanol gasoline

 The invention relates to a methanol gasoline core mother liquor and methanol gasoline prepared by using the mother liquor. Background technique

 According to the BP World Energy Statistical Yearbook, as of the end of 2011, the global oil reserves were about 1.653 trillion barrels. According to the current globally very conservative consumption rate of 0.8 billion barrels per day, the current world oil reserves are available. Global consumption for 54 years.

 As a limited resource, oil will become more and more tense in the face of the development of world industrialization and the heavy use of automobiles. The price of oil has risen from 10.58 US dollars at the end of the last century to 100 US dollars now. The rate of increase is fast in the history of oil. Rarely, it is rare in other large resource products. The soaring oil prices are forcing countries around the world to find alternative energy sources.

 China's oil reserves only account for 3% of the world, and oil consumption has soared, household cars have increased, and economic costs have increased. Therefore, China's energy experts agree that energy security strategies must be implemented and every effort must be made to develop oil substitute fuels. In the past two decades, China has accelerated the implementation of its energy strategy and vigorously sought and developed alternative fuels for petroleum.

 China is a country that is poor in oil, low in gas and rich in coal. Starting from China's national conditions, finding alternative clean energy from coal-based energy is an important way to solve energy security and sustainable development. On the other hand, with the rapid development of the automobile industry, the rapid increase of urban and rural vehicles has been brought about, and the large use of automobile fuel gasoline has caused serious pollution to the atmospheric environment and seriously threatened the living environment of human beings. Therefore, high-volume, large-scale replacement of automotive cleaning fuels has emerged to address the current over-reliance on oil and the increasing environmental concerns. Among them, the most widely used and fastest growing is methanol gasoline. Due to the wide range of methanol sources, clean fuels and low environmental pollution, it is widely concerned by the automotive industry. Therefore, it is imperative to develop methanol to replace automobile fuel.

China has accumulated sufficient technical basis for designing, manufacturing and operating large-scale methanol plants: Large-scale gasification furnaces with coal-water slurry as raw materials have been in operation for many years, enabling long-cycle operation; new coal-water slurry gasifiers and dry coal pressurization Gasifiers are being actively developed; various low-energy natural gas steam reforming technologies have been mastered; low-cost natural gas conversion to syngas technology using air as a gasifying agent has been developed; various decarbonization and desulfurization processes have been matured. In industrial production; conversion, fine desulfurization, methanol synthesis catalysts have been domestically produced; new methanol synthesis reactor has formed a patent technology - - Technology; Rectification equipment has reached energy saving and optimization levels. At present, China has mastered the design technology of building a 100,000-300,000 t / a single series methanol plant. Therefore, the use of coal or natural gas to produce methanol, rich sources of raw materials, mature production technology, reasonable price of methanol; methanol gasoline is a high-energy devaluation fuel. At normal temperature, methanol is a liquid, and its storage, transportation, and use are as convenient as gasoline and diesel. The addition of methanol can significantly reduce the emission of harmful substances and is a clean vehicle fuel. Methanol gasoline burns less than harmful substances in the exhaust of the No. 90 gasoline, and has less impact on environmental pollution. The US "DOC" Research Center used 10%-10% gasoline containing methanol to test the results of 10 kinds of cars. When using methanol gasoline on a general gasoline engine, the carbon monoxide in the combustion exhaust gas is reduced by about 30% compared with gasoline, the nitrogen oxides are reduced by 30%-50% compared with gasoline, and the unburned hydrocarbons are reduced by 30%-60%. . The development of methanol gasoline is conducive to the environmental protection of the city. Methanol is the most promising clean fuel in the 21st century. Summary of the invention
