Abstract

The application of the invention relates to the technical field of vehicle fuel, and particularly discloses a methanol gasoline and a preparation method of the methanol gasoline. The methanol gasolinecomprises methyl alcohol, gasoline, a mother liquor of a core agent, and a gas resistance reduction agent at certain ratio, the gas resistance reduction agent comprises acetal, ketal, dicarboxylic ester, a natural oil derivative, a metal corrosion inhibitor and a rubber swelling inhibitor; the methyl alcohol, the mother liquor of the core agent, the gas resistance reduction agent and the gasolineare sequentially added into a reaction kettle according to the material ratio and are fully stirred to prepare the methanol gasoline; the prepared methanol gasoline is high in combustion value, goodin antiknock property, anti-swelling and corrosion resistance and low in saturated vapor pressure, the adapted temperature difference is large, the problems of low-temperature phase splitting and hightemperature gas resistance basically do not exist, and the methanol gasoline is excellent in economical efficiency, environmental protection property and safety.

Description

technical field [0001] The invention relates to the technical field of vehicle fuel, in particular to a methanol gasoline and a preparation method thereof. Background technique [0002] Energy depletion and environmental pollution are serious problems facing the world. With the rapid growth of car ownership, the contradiction between the supply and demand of petroleum-based vehicle fuels worldwide has become increasingly prominent, the total amount of petroleum consumed by automobile engines is huge, and exhaust emissions have become one of the main sources of air pollution today; from resources, environment, economy, etc. Considering all aspects, the research and development of clean alternative fuels and the rational use of resources have become increasingly prominent practical issues. [0003] Methanol fuel is rich in sources, can reduce vehicle operating costs, and save a lot of oil resources. Therefore, it has practical and economic significance to use methanol as an a...
