Methanol is a bulk organic chemical raw material with abundant resources, which can be used in coal conversion synthesis, natural gas preparation and wood and even garbage production. In order to save petroleum resources, since the 1930s, countries all over the world have conducted in-depth and extensive research on methanol fuel. With the rise of China's economy, the research and application of methanol fuel has made a major breakthrough in technology. For example, M 15, M30, M50, M65 and other clean methanol gasoline developed by Luohe Petrochemical Group Co., Ltd. have been widely used in practice. . . Necessity of developing methanol fuel \x0d\ China has limited oil reserves. At present, the proven oil reserves can only be mined for about 20 years, and it has become a net oil importer since 1993. Oil imports in 2000 were 70 million tons. In 2002, the daily consumption reached 50 1000 barrels, surpassing Japan and becoming the second largest oil consumer in the world after the United States. China imports more than 60% of its oil and is a major buyer of oil in the world. China's modernization is mainly based on oil imports, which has neither energy security nor national security. Therefore, for sustainable development and growth, energy security has become an urgent problem to be solved in China. \x0d\ Although the Chinese government has adopted a series of multi-directional oil import strategies, vigorously promoted the exploration and development of oil and gas in the central and western regions of China and offshore areas, and promoted multi-channel oil import, no matter how hard it tries, it will still mainly rely on oil imports from the Middle East. The government has made a lot of efforts to reduce oil imports, except for the development and application of methanol fuel caps in the following aspects: \x0d\ 1. Introduction of coal-to-oil technology device. This is a technology developed by Germany in the last century, but there is no major technological breakthrough so far. The oil consumption per ton of coal is as high as 4. 15 tons, and there is electricity, so the construction cost is huge. A coal-to-oil plant with an annual output of 2 million tons needs to invest 20 billion yuan, and it is almost impossible to rely on the state to invest a lot of money to build it. \x0d\ 2。 Aged grains produce ethanol instead of gasoline. In May, 2002, Henan Province took the lead in the compulsory promotion and use by the government in Zhengzhou, Luoyang and Nanyang, but the promotion situation was not ideal, in fact, 3. 5 tons of grain production 1 ton of ethanol still needs 3. Using 5 tons of coal as heat source to concentrate ethanol, 1.5 tons of ethanol will replace 1 ton of gasoline, and the price of ethanol is as high as 4,600 yuan/ton, equivalent to 7,000 yuan/ton of gasoline, which not only causes great waste of resources, but also causes secondary pollution to the environment. Converting grain into ethanol instead of oil is neither in line with the national conditions nor with the rational allocation of resources. \x0d\ 3, compressed natural gas instead of gasoline. Each car needs to invest about 654.38+0000 yuan. The cost of natural gas is higher than coal-based methanol. To build a compressed natural gas supply station, domestic equipment needs to invest 4 million yuan, imported equipment needs 30 million yuan, and a new methanol fuel gas station only needs 250 thousand yuan. If it is built in the original gas station, it only needs 654.38+0000 yuan, and the natural gas distribution is limited, which is not suitable for nationwide promotion. \x0d\ 4。 The country is also conducting research on dimethyl ether, electric vehicles and lithium battery vehicles, but it will take a long time to realize the industrialization of technology. . . China's energy structure is characterized by more coal and less oil. It is estimated that China's coal resources will be available for exploitation for nearly 100 years, and the direct utilization efficiency of coal resources is low and the pollution is serious. If methanol fuel is developed with coal as raw material, it can not only maintain China's energy security for nearly a hundred years, but also optimize the energy structure, reduce the consumption of coal and garbage, and recycle them, which is an inevitable choice for human sustainable development.
