Description

A kind of blended gasoline and preparation method thereof

Technical field

The present invention relates to gasoline preparation field, particularly a kind of blended gasoline, also relate to a kind of preparation method of blended gasoline.

Background technology

The gasoline overwhelming majority supplied in the market is the component oil that refinery crude oil obtains through fractionation by distillation and the processing of complicated production technique, the following defect of ubiquity: one is containing the component of easily seeing photolysis in gasoline, easy generation is as the heavy metal element such as manganese, iron, make gasoline be not easy to store, and use the wearing and tearing that will cause vehicle motor and oil piping system for a long time; Two is that sulfur content in gasoline is high, directly causes nitrogen oxide in tail gas, sulfurous gas and granular material discharged aggravation, thus affects Air quality.On market, regular gasoline sulphur content is mostly in 50-150ppm scope, and part is in 150-500ppm scope, and 2014 have come into effect state four standard, and sulphur content is 50ppm, and in state five standard, sulphur content is 10ppm, expects ability in 2017 and realizes.And the generation often with waste material, waste gas and waste water in the course of processing of above-mentioned gasoline, very easily contaminate environment, and the production cost of above-mentioned gasoline is high, productive rate is low, the demand of Vehicles Collected from Market can not be met, its associated resources is except small part is as except industrial chemicals, major part is not utilized, and there is serious problem of resource waste.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of blended gasoline, to solve the above-mentioned multinomial defect caused in prior art.

For achieving the above object, the invention provides following technical scheme: a kind of blended gasoline, it is characterized in that: comprise following composition, be by mass percentage: carbon five 35-40%, cracking aromatic hydrocarbons 35-40%, corrosion inhibitor 1.6-1.8%, antioxidant 1.5-1.7%, lubricant 1.2-1.8%, methyl tertiary butyl ether 2-4%, benzaminic acid 2-4%, dimethyl phosphate 1.4-1.6%, petroleum naphtha 6-8%, stablizer 1.6-2.2%, surplus is sodium hydroxide.

Preferably, described corrosion inhibitor comprises benzotriazole and oleic imidazolinone, and described benzotriazole and oleic imidazolinone quality proportioning are 2:3.

Preferably, described antioxidant is BHT501.

Preferably, described lubricant is whiteruss.

Preferably, described stablizer comprises butanone and glycerol, and the mass ratio of described butanone and glycerol is 2:3.

A preparation method for blended gasoline, comprises the following steps:

1) at 23 DEG C, by carbon five, cracking aromatic hydrocarbons, sodium hydroxide, methyl tertiary butyl ether, benzaminic acid, dimethyl phosphate and petroleum naphtha mixing and stirring;

2) again corrosion inhibitor, antioxidant and lubricant are added in said mixture, stir;

3) and then add stablizer, stir.

The beneficial effect of above technical scheme is adopted to be: a kind of blended gasoline of the present invention, the starting material that all additives all adopt abundance, stable performance, renewable, post combustion emission clean, Blending is simple, low production cost, and production process is discharged without waste water,waste gas and industrial residue; Popularization of the present invention can available protecting environment, reduce fuel cost, save petroleum resources; The present invention has better protecting effect to the power system of vehicle and oil supply system, its dynamic performance, oilness, anticorrosive, anti-oxidant, low-temperature ignition after actual test verification, oil consumption, micro-metal discharge, sulphur emissions, mutual solubility, vapour lock etc. are all better than 97# state 5 normal benzene; Ignition trigger performance is good: ignition trigger performance is more superior, and northeastward etc. low temp area advantage is very obvious; Flame resistivity is high: compared with equivalent like product, and the present invention is high, and pure blended gasoline can run out of more milimeter number, more fuel-efficient; Stability is strong: the present invention is high, and pure blended gasoline places not stratified, nondiscoloration half a year more than, still can reach quality testing standard, can not decomposite heavy metal under condition of being exposed to the sun, longer than the storage time with like product; Mutual solubility is good: be used alternatingly with any same label gasoline on the market, have no effect to car body.
