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 belongs to the technical field of gasoline additives and relates to an alcohol ester type compound gasoline additive and a preparation method thereof. The compound gasoline additive is prepared from, by weight, 75-80% of methyl alcohol, 5-15% of ethyl alcohol, 5-15% of ethyl acetate and 5-10% of fatsia japonica seed oil by processing. The alcohol ester type compound gasoline additiveis high in stability and uniformity and excellent in oxidation resistance and carbon deposition removal. The preparation method of the alcohol ester type compound gasoline additive is reasonable in process and high in controllability, and acquired compound gasoline additive products are high in quality uniformity. In specific use, the alcohol ester type compound gasoline additive and the common gasoline (92, 95 or 98 RON) are added by a volume ratio of 1:8-10 and well mixed. High dispersity is achieved, and oxidation resistance and carbon deposition removal performances of gasoline are improved.

Description

technical field [0001] The invention relates to an alcohol ester compound gasoline additive and a preparation method thereof, belonging to the technical field of gasoline additives. Background technique [0002] Methanol can be converted from raw materials such as petroleum, coal, natural gas, and wood fiber. 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 driv...
