Abstract

The invention provides methanol fuel and a preparation method thereof, and relates to the technical field of fuel. The methanol fuel comprises 95%-99% of methanol and 1%-5% of an additive, and the additive is 1-butyl-3-methylimidazolium tetrafluoroborate, linear alkyl acid, a polystyrene-polyether type amphiphilic block copolymer, ethylene glycol monobutyl ether and N, N-dihydroxyethyl p-toluidine. The additive has good compatibility with methanol, the octane number of the methanol fuel is increased by 4-6 units on the premise that the quality of the methanol fuel is not affected, the combustion performance and the lubricating performance of the methanol fuel are improved, the low-temperature fluidity of the methanol fuel is improved, corrosion to external factor metal is effectively blocked, and the application prospect is good.
