Description

Ethanol gasoline for motor-vehicle and preparation method thereof

Technical field

The present invention relates to clean fuel, relate in particular to ethanol gasoline for motor-vehicle and preparation method thereof.

Background technology

Along with petroleum resources are more and more poorer, and often receive the influence of political instability factor, oil price also raises day by day.At present, China's fuel gasoline consumption is huge, has increased the consumption of the energy greatly, adopts traditional gasoline to bring the pollution of motor vehicle exhaust again simultaneously.Therefore, from long-range viewpoint, seek a kind of ideal oil fuel surrogate, oneself becomes one of important subject in the contemporary science and technology field.The current appearance that many new gasoline and automobile fuel are also arranged, but the cost that has is higher, have automobile is used brings counter productive, and pollution emission is unfavorable etc.

Chinese invention patent application (publication number is CN1316487) discloses a kind of environment protection gasoline, mainly is made up of methyl alcohol (or ethanol), denaturing agent and processed oil.That this invention is made is simple, octane value is high, explosive power is strong, flameholding, the clean pollution of waste gas lack, and saves gasoline widely.

Chinese invention patent application (publication number is CN1621501) discloses a kind of synthetic gasoline; Produce by following steps: under normal temperature and pressure conditions; Ethanol 25%, benzene mixed 35%, 93# regular gasoline 39.2% are mixed; Carry out abundant batch mixing after adding multipurpose additive 0.8% again, elimination impurity gets final product.

Chinese invention patent application (publication number is CN1810937) discloses a kind of motor vehicle mixed green gasoline and has formed formulated by the following weight proportion raw material: gasoline 65-90%, methyl alcohol 5-25%, ethanol 5-25%, solubility promoter 0.3-3%.On motor vehicle, use mixed green gasoline provided by the invention, per 100 km consumption oil ratio regular gasoline fuel-economizing 8%, the tail gas hazardous emission reduces 70%.

Chinese invention patent application (publication number CN1737088) discloses a kind of alcohol gasoline mixing liquid fuel for vehicular, contains following components in percentage by volume: gasoline 10～90%; Alcohols mixture 7～89%; Sherwood oil 1～10%.The popularization of clean environment-friendly fuel of the present invention can improve atmospheric environment, improves quality of residents'life, can partly substitute petroleum resources.

Summary of the invention

Bring the pollution problem of motor vehicle exhaust again for the in short supply and traditional gasoline that solves existing petroleum resources; The purpose of this invention is to provide a kind of ethanol gasoline for motor-vehicle and preparation method thereof, characteristics such as production cost is low, octane value is high, explosive power is strong, clean environment firendly that it has.

In order to realize above-mentioned purpose, the technical scheme below the present invention has adopted:

Ethanol gasoline for motor-vehicle is made up of the raw material of following component: industrial spirit 15.0～25.0%, Virahol 0.60～5.0%, gasoline 30.0～50.0%, methylal 29.0～45.0%, the trimethyl carbinol 4.0～15.0%, DIPE, 2.0～10.0%, petroleum naphtha 1～5% by weight percentage; Above-mentioned raw material is formed the atlapulgite that after mixing, adds 1～6% weight percent, stir the physical and chemical reaction after-filtration and promptly get described ethanol gasoline for motor-vehicle.

As preferably, form by the raw material of following component by weight percentage: industrial spirit 17.0～20.0%, Virahol 0.60～2.0%, gasoline 30.0～50.0%, methylal 32.0～40.0%, the trimethyl carbinol 4.0～8.0%, DIPE 2.0～8.0%, petroleum naphtha 1～3%.

As preferably, the add-on of atlapulgite is 1～4%.

As most preferably, form by the raw material of following component by weight percentage: industrial spirit 17.0%, Virahol 1.0%, gasoline 33.0%, methylal 35.0%, the trimethyl carbinol 5.0%, DIPE 5.0%, petroleum naphtha 2.0%; Above-mentioned raw material is formed the atlapulgite that after mixing, adds 2.0% weight percent, stir the physical and chemical reaction after-filtration and promptly get described ethanol gasoline for motor-vehicle.

The preparation method of above-mentioned ethanol gasoline for motor-vehicle, this method comprise the industrial spirit of formula ratio, Virahol, gasoline, methylal, the trimethyl carbinol, DIPE and petroleum naphtha are mixed; Add the formula ratio atlapulgite then, stir 0.5～2 hour after-filtration of physical and chemical reaction and promptly get described ethanol gasoline for motor-vehicle.

Industrial spirit of the present invention is the waste material on the medicine industry, has practiced thrift cost on the one hand, has reached the effect of waste disposal on the other hand.But owing to add industrial spirit, the octane value of gasoline, explosive power all reduce greatly, can't use as gasoline.Therefore, add Virahol, methylal, the trimethyl carbinol, DIPE and petroleum naphtha in the prescription of the present invention, mentioned ethanol gasoline for motor-vehicle octane value and explosive power.Particularly added methylal among the present invention, methylal is a waste material of producing Glyphosate 62 IPA Salt, refines through processing to form, and the present invention adds the problem of utilizing that methylal has solved industrial methylal.

Simultaneously,, contain the foreign material of moisture and other impurity, particularly sulfur-bearing in the industrial spirit owing to the industrial spirit and the methylal that add among the present invention, bigger to the mover damage of automobile.Therefore, the present invention must add the atlapulgite of 1～6% weight percent after mixing, and removing moisture and other impurity, gum deposit on the cylinder sleeve that permanent burning can mover, the piston need not add other lubricant.

The present invention has the high and strong characteristics of explosive power of octane value, and according to the detection of Jiangsu Supervision and Inspection Institute for Product Quality, octane value of the present invention reaches 95RON, and uprising index reaches 89.Simultaneously, in gasoline, add industrial spirit, reduce production costs, exhaust emissions is smokeless, odorlessness, on motor vehicle, uses ethanol gasoline for motor-vehicle provided by the invention, per 100 km consumption oil ratio regular gasoline fuel-economizing 5%, and the tail gas hazardous emission reduces 75%.This invention can reduce automobile exhaust pollution to greatest extent, and motor car engine is had no adverse effects, and the popularization of clean environment-friendly fuel of the present invention can improve atmospheric environment, improves quality of residents'life, can partly substitute existing gasoline.
