Abstract

This invention discloses a method for preparing additive for M80-M90 or E80-E90 alcohol-based automobile fuel. When 10-20 parts of the additive is added into 80-90 parts of methanol or ethanol, alcohol-based automobile fuel can be obtained, which can be used as a substitute for gasoline without the need for adjusting or replaing present engines. The alcohol-based automobile fuel has comparable power to commercialized leadless gasoline. Besides, a fuel energizer is added into the additive, which can convert methanol whose caloric value is 49% of leadless gasoline into automobile fuel with high power.

Description

technical field [0001] The invention relates to a method for preparing an alcohol-based vehicle fuel additive, which belongs to the field of fuel chemical industry. Background technique [0002] Under the background of world energy shortage, all countries are investing manpower and material resources to actively develop alternative energy sources. Methanol gasoline and ethanol gasoline are the leaders in alternative energy in the market. Currently on the market, the amount of ethanol gasoline blended with ethanol is 10%, and the amount of methanol gasoline blended with methanol is 15-30%, both of which are blended with low proportions. According to the information obtained from the National Alcohol Ether Fuel Association, the country is very interested in the blending of methanol and ethanol with a high proportion, that is, the amount of alcohol blended with 85-100%. If it can be realized technically, it can fundamentally solve the problem of energy substitution in our coun...
