Abstract

The invention relates to a gasoline additive which comprises the following components in parts by weight: 6-10 parts of iso-octane, 5-8 parts of ethylene glycol tert-butyl ether, 3-4 parts of diaminoanisole, 7-12 parts of paracyclophane, 20-30 parts of toluene, 10-12 parts of isooctanol, 2-4 parts of tetraethylenepentamine, 1-2 parts of polyisobutylene succinimide, 1-3 parts of eicosanoic acid, 2-4 parts of dimethyl carbonate and 2-5 parts of an additive. The invention also relates to a preparation method of the gasoline additive. According to the invention, Ce particles are generated during the combustion process of the gasoline additive, rare earth oxides can effectively improve and prolong the efficiency of the catalyst and improve the thermal stability of the catalyst at high temperatures, and cerium composite oxides at high temperatures can maintain the crystal grain structure to be unchanged, so that the oxygen storage and release processes of Ce are easy to realize; the Ce particles can effectively reduce the reaction activation energy during the combustion process, so that the gasoline can realize complete combustion at relatively low temperatures, and the emission of pollutants in the tail gas is reduced.

Description

technical field [0001] The invention relates to the technical field of gasoline additives, in particular to a gasoline additive capable of increasing the octane number of gasoline, and also relates to a preparation method of the gasoline additive. Background technique [0002] Gasoline additive is an abbreviation of fuel additive. It is to make up for the quality problems of the fuel itself and the shortcomings of the mechanical manufacturing limit of motor vehicles, so that the gasoline engine can overcome the chilling effect and gap effect, and clear the intake valve and electric injector. The carbon deposits in the diesel engine can overcome the problem of finer atomization of the injector and the generation of residual oil after dripping, so that both gasoline and diesel engine vehicles can protect the engine working conditions and achieve more complete and complete combustion of fuel , so as to achieve the effects of removing carbon deposits, saving fuel, reducing emiss...
