Abstract

The invention belongs-the field of alcohol ether low-carbon clean energy, and discloses a methanol fuel for vehicles. The methanol fuel for the vehicles is prepared from 15-96 wt% of methanol, 0.5-2 wt% of a multi-carbon alcohol, 2.5-10 wt% of aliphatic ether, 0.5-57.5 wt% of a hydrocarbon compound, 0.4-15 wt% of an aromatic hydrocarbon and 0.1-0.5 wt% of an additive, wherein the multi-carbon alcohol is a fatty alcohol with the carbon number being 3-8 and the molecular formula being CnH2n+1OH, the hydrocarbon compound is gasoline only containing hydrogen and carbon, and the aromatic hydrocarbon is a benzene ring-containing hydrocarbon with the carbon number being larger than or equal-7 and the general formula being CnH2n-6. Organic acids, alkylamine and alkynyl ester amine are subjected toorganic synthesis modification by using the additive in the methanol fuel for the vehicle in order to integrate multiple organic groups, so that the problems of layering when meeting water and low temperature, rubber swelling, metal corrosion, hot air resistance and cold start of methanol fuels for vehicles are solved.

Description

technical field [0001] The invention relates to the field of alcohol ether low-carbon clean energy, in particular to a methanol fuel for vehicles. Background technique [0002] In 2018, my country's oil consumption reached more than 500 million tons, while self-produced crude oil has hovered around 200 million tons for many years, the dependence on foreign imports exceeded 70%, and the dependence on natural gas imports reached 46%. "Short of oil, less gas, rich in coal" is my country's basic energy structure. If there is an over-reliance on oil imports, there is a huge risk to national energy security. In order to accelerate the application of methanol vehicles and realize the diversification of vehicle fuels, the Ministry of Industry and Information Technology and other eight national ministries and commissions require that according to local conditions, active and safe, safe and controllable principles, the focus should be on Shanxi, Shaanxi, Guizhou, Gansu and other reso...
