AI Technical Summary

Problems solved by technology

However, methanol has strong polarity, and the methanol gasoline formed has poor stability, and it is prone to turbidity and stratification when it encounters a small amount of water or a low temperature environment.
When used in driving, methanol gasoline will easily produce air lock in summer, but difficult to ignite in winter

Abstract

The invention relates to methanol gasoline additive; counted by mass percent, raw materials of the additive disclosed by The invention comprise 20-30% of alcohols mixture, 30-35% of ethers mixture, 10-15% of oleic acid or dimer acid and C1-3 fatty amine, 20-26% of methylbenzene or isopropylbenzene, 2-6% of 2,6-butylatedhydroxytoluene, and 1-5% of OP-15; the alcohols mixture comprises propyl alcohol, butanol and amyl alcohol; and the ethers mixture comprises dimethoxymethane or 1,2-dimethoxyethane and glycol ether. After the additive of The invention is added to high-proportion methanol gasoline (such as M60-M80 methanol gasoline), the additive can comprehensively solve an obvious defect that the high-proportion methanol gasoline is made as vehicle fuel, thus, physicochemical quality index and actual operational performance of the high-proportion methanol gasoline are accorded with a demand of gasoline vehicle fuel; in addition, the methanol gasoline additive can be used completely without refitting automobiles.

Description

technical field [0001] The invention belongs to the field of methanol gasoline additives, in particular to a methanol gasoline additive and methanol gasoline containing the additive. Background technique [0002] Methanol can be converted from petroleum, coal, natural gas, wood fiber and other raw materials, so it has a wide range of sources, mature production technology and low cost. Methanol itself is an oxygen-containing compound, which can be completely combusted, has no pollution to the environment, has a high octane number, and has good power performance, making it an ideal clean fuel. [0003] Anhydrous methanol can be completely mixed with commercial gasoline, so it can be used as a substitute for gasoline and become a vehicle fuel. However, methanol has strong polarity, and the methanol gasoline formed has poor stability, and turbidity and stratification are prone to occur when encountering a small amount of water or a low temperature environment. When used in dri...
