Problems solved by technology

[0004] However, in the process of using gasoline, it is easy to have problems such as cold start of solubilization, high temperature air resistance, water stratification, oily alcohol stability and insufficient power, which affect the rapid development of alcohol gasoline
[0005] Chinese patent CN108913238A discloses a methanol-gasoline composite additive and its preparation method, which solves the problem that the existing methanol-gasoline composite additive contains a large amount of emulsifying water-melting agent, which will affect the quality of the oil to a certain extent
But, this invention is not obvious to the solution effect of methanol gasoline's water stratification and high temperature air resistance problems
[0007] Therefore, the present invention provides a compound additive for alcohol gasoline and a preparation method thereof, aiming at problems such as moisture stratification, high-temperature air resistance, and insufficient power of alcohol gasoline.

Description

technical field [0001] The invention relates to the technical field of gasoline additives, in particular to a compound additive for alcohol gasoline and a preparation method thereof. Background technique [0002] At present, the problem of energy shortage and environmental pollution is becoming more and more serious, mainly due to unrestrained energy development and low utilization rate. The petroleum resources used in the past are non-renewable resources. With the continuous increase of demand, the reserves of petroleum resources are getting smaller and smaller. [0003] The development and utilization of alcohol clean new energy has become the best alternative resource for petroleum resources. Alcohol-based gasoline has incomparable advantages. On the one hand, it can optimize the energy structure, and on the other hand, it can alleviate the contradiction between oil supply and demand, and expand it into a long-term development direction for research. [0004] However, i...
