Preparation method of fuel additive

Abstract

The invention discloses a preparation method of a fuel additive and belongs to the technical field of fuel additives. The preparation method comprises the steps that firstly, snail shells are taken and smashed for ultrasonic oscillation, filtrate and filtration residues are respectively collected after filtration, then polyisobutylene, maleic anhydride and the like are subjected to stirring reaction, pH is regulated, standing is performed for layering, an organic phase is collected to obtain polyisobutylene succinimide, then silver oxide, aluminum oxide and the like are mixed with the filtration residues, the mixture is ball-milled into powder, the mixed powder is mixed with methyl alcohol to obtain mixed liquid, the mixed liquid is mixed with the filtrate, the polyisobutylene succinimide and the like to obtain a base material, and finally the base material, castor oil, potassium nitrate and the like are stirred and discharged to obtain the fuel additive. The prepared fuel additive is suitable for long-term storage and transportation, an oil layer emulsification phenomenon does not occur, engine running is not affected, the fuel additive does not contain sulfur, phosphorus and other substances, is green, environmentally friendly, does not destroy the environment or harm human and has a broad application prospect.

Description

technical field [0001] The invention discloses a preparation method of a fuel additive and belongs to the technical field of fuel additive preparation. Background technique [0002] Engine carbon deposits will slowly deposit inside the engine without knowing it. When people ignore the existence of carbon deposits, it will slowly swallow engine power, reduce fuel economy, worsen emissions, and cause a series of engine failures. In addition, the tail gas emitted by automobiles is harmful except for the combustion products of carbon dioxide and water vapor, which are harmless components. [0003] Some toxic substances in the tail gas emitted by automobile engines are caused by incomplete combustion of fuel or low gas temperature, such as carbon monoxide, hydrocarbons and nitrogen oxides. Another part of toxic substances is nitrogen oxides produced by the high temperature and high pressure environment in the combustion chamber; in addition, there are sulfur dioxide and lead com...

Problems solved by technology

[0006] The technical problem mainly solved by the present invention is to provide a preparation method of a fuel additive for the current existing fuel additives which are easy to emulsify and affect the normal operation of the engine and contain sulfur, phosphorus and other substances, which will pollute the environment and cause harm to the human body. Method Firstly, the shell of the snail was taken and crushed for ultrasonic oscillation, the filtrate and the filter residue were collected by filtration, and then polyisobutene, maleic anhydride, etc. were stirred and reacted, the pH was adjusted, and the layers were left to stand, and the organic phase was collected to obtain polyisobutene imide. Silver oxide, aluminum oxide, etc. are mixed with the above-mentioned filter residue and ball-milled into powder, and the mixed powder is stirred with anhydrous methanol to obtain a mixed solution, and then the mixed solution is mixed with the above-mentioned filtrate and polyisobutylene imide to obtain a base material, and finally the base fuel oil, castor oil, potassium nitrate, etc., can be stirred and discharged, and the fuel additive can be obtained. The fuel additive prepared by the present invention is easy to store and transport for a long time, and there will be no emulsification of the oil layer, and will not affect the operation of the engine. It does not contain sulfur, phosphorus and other substances, is green and environmentally friendly, will not cause damage to the environment and human body, and has broad application prospects
