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 fil

example 1

[0019] First, select 5 snails with a weight of 30 g, wash them with deionized water for 3 times, smash the shells of the snails after cleaning, peel off the shells, crush the shells with a pulverizer for 10 minutes, collect the crushed objects, and add them to a beaker. Add 100mL of absolute ethanol to the beaker, place it in an ultrasonic oscillator, ultrasonicate at 220W for 30min, then filter, collect the filtrate and filter residue respectively, and set aside; then weigh 5g of polyisobutylene and add it to a three-necked flask with a thermometer and a reflux device , put the flask in an oil bath, heat up to 80°C, then add 1g of maleic anhydride, stir for 30min, then heat up to 160°C, then add 2mL of 1-amino-8-naphthol-3,6-disulfone acid, stirred for 2 hours, after the reaction was completed, added diethylene polyethylamine, adjusted the pH to 7.0, then added 100mL deionized water, stirred for 10 minutes, allowed to stand and separated, collected the organic phase, that is, ...

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...
