Abstract

The invention provides a composite additive for M5-M25 methanol gasoline fuels and a methanol gasoline thereof. The composite additive is prepared from the following raw materials in percentage by weight: 22-36% of alcohol mixture, 12-24% of ester mixture, 14-28% of ether mixture, 13-24% of aromatic mixture, 4-8% of dimethoxy tetrahydrofuran, 2-6% of alkenyl succinic acid, 2-6% of polylysine, 3-6% of 2,4-dimethyl-6-bert-butyl phenol, 1-8% of tetraethylenepentamine and 2-5% of 2-methylbenzothiazole. The methanol gasoline prepared by the composite additive does not have the phenomenon of air resistance at high temperature, and can still keep the transparent, clear and unstratified state at low temperature; and thus, the methanol gasoline has stable properties and is convenient for storage and use.

Description

technical field [0001] The invention relates to the field of clean fuels, in particular to a composite additive for M5-M25 methanol gasoline fuel and the methanol gasoline. Background technique [0002] At present, the oil resources on the earth are depleted day by day, but with the development of world economic construction, the amount of oil is increasing day by day. Faced with this severe situation, it is imperative to speed up the search for alternative fuels for internal combustion engines and to develop clean energy sources in order to cope with the oil crisis and improve the security of fuel supply; prepare for the smooth transition of fuel types after the exhaustion of oil resources, and improve It is urgent to improve the application efficiency of energy, open up new fields of energy application, reduce pollution, and protect the ecological environment. [0003] Alcohol is the most substitutable fuel for internal combustion engines other than petroleum and natural ...
