High-clean aviation alcohol-hydrocarbon composite vehicle fuel additive, preparation method and fuel

Abstract

The invention relates to a high-cleanness navigation alcohol hydrocarbon compound vehicle fuel additive. The high-cleanness navigation alcohol hydrocarbon compound vehicle fuel additive is prepared by raw materials including, by weight, 0.1-0.15 parts of petroleum ether, 18-39 parts of n-butyl alcohol, 2-25 parts of methyl alcohol, 3-14 parts of acetone, 1.8-1.9 parts of tert-butyl alcohol, 3.5-8.5 parts of dodecanol, 2-7 parts of 2,6-di-tert-butyl-4-methylphenol, 1.4-4.8 parts of copper corrosion inhibitor, 4.5-16 parts of isopropyl ether, 2-5 parts of cyclopentadienyl manganese tricarbonyl and 1.5-4 parts of CH agent. The invention further relates to gasoline and a preparation method of the high-cleanness navigation alcohol hydrocarbon compound vehicle fuel additive. The high-cleanness navigation alcohol hydrocarbon compound vehicle fuel additive has a function of inhibiting oil-water dissociation caused after mixing of the methyl alcohol and gasoline meeting national standards. The fuel has the advantages of obviously small relative molecular mass, high latent heat of evaporation, high heat efficiency, capability of substituting for the gasoline meeting the national standards, full combustion, environment friendliness, good emission reduction effect and high economy and safety.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to a high-clean aviation alcohol-hydrocarbon composite vehicle fuel additive, a preparation method and fuel. Background technique [0002] Gasoline is a volatile and flammable hydrocarbon mixture liquid obtained from fractionation or cracking or cracking of petroleum, which can be used as fuel. Gasoline additive is an abbreviation of fuel additive, and generally includes diesel additives, which are used to make up for the quality problems of the fuel itself and the shortcomings of the mechanical manufacturing limit of motor vehicles, so as to overcome the chilling effect and crevice effect on gasoline engines. The carbon deposits in intake valves and electric nozzles can overcome the problems of finer atomization of fuel injectors and residual oil dripping for diesel engines, and can protect the working conditions of gasoline and diesel engines and achieve better fuel consumption. ...

AI Technical Summary

Problems solved by technology

However, the above-mentioned methanol gasoline additive has the problem that it is difficult to suppress the phenomenon of oil-water stratification after the mixture of methanol and national standard gasoline, and the relative molecular mass of gasoline after adding the above-mentioned methanol gasoline additive is relatively large, and the ignition and explosion concentration of gasoline vapor is low, thereby It has the problems of low evaporation heat efficiency, low ignition point and easy explosion
