Technical Field

Background

With the rapid development of the global economy and the rapid expansion of the world population, the demand of human energy is also sharply increased. Currently, energy issues have become a major bottleneck in the development of global economy. In recent years, the world's consumption of oil has been increasing, so that the storage of oil energy as a non-renewable resource has been decreasing, and the storage and recovery ratio of oil and natural gas is far behind that of coal. Currently, various countries around the world are working on the development of alternative fuels, particularly in an attempt to develop coal-based fuel routes to alleviate the dilemma caused by the energy crisis.

Seeking alternative fuels generally, the following are considered: whether the source is rich and stable; the production cost cannot be too high; is liquid fuel and has good adaptability with the prior vehicle; the energy source is clean energy, and the production and preparation process is environment-friendly; after the vehicle is used, the dynamic property and the economic change of the automobile are not large, and the improvement is better. Furthermore, the alternative fuel is preferably a renewable resource. At present, alcohols are the most available fuels for internal combustion engines besides petroleum and natural gas, and are a new hope for replacing petroleum fuels, wherein methanol fuel is more preferred.

The methanol as the alternative fuel is particularly suitable for the national conditions of China. Currently, coal-based methanol is one of the main products in the coal chemical industry in China, is in a state of excess capacity and is low in price. The development of the methanol gasoline can open up a new application way for the coal chemical industry chain, simultaneously relieve the contradiction of the shortage of gasoline supply and demand, and has remarkable economic and social benefits. China has been carrying out research, development and test for 20 years in the field of vehicle methanol gasoline, has made certain progress, and particularly has had certain market scale in the aspect of research and application of low-proportion methanol gasoline. However, the research and application of high-proportion methanol gasoline are slightly lagged. The problems of incompatibility, poor water resistance, difficult cold start of automobiles, air resistance, corrosion of metal parts, rubber and plastic swelling and cracking and the like in the use of low-proportion methanol gasoline are caused by the increase of the proportion of methanol.
