Abstract
The present invention relates to methanol gasoline for vehicles. The present invention is characterized in that the weight ratio of methanol to gasoline, namely a methanol gasoline ratio, is from 3/7 to 7/3; one cosolvent of ester alkyl phosphoric acid and isomerism alcohol accounting for 0.005 to 0.01% of the total amount is added into the methanol gasoline; organic metallic compounds as combustion promoters accounting for 0.001 to 0.005% of the total amount are added into the methanol gasoline. The methanol gasoline for vehicles has the advantages of large methanol content, high octane value, no delamination after long-time storage, complete combustion, quick and strong speed increase when the engine raises the throttle, little tail gas emission pollution, easy CO2 and H2O generation by complete combustion and a few toxic and harmful substances, such as nitrides, sulfides, etc.
Description
The invention belongs to the gasoline field, specifically is a kind of Vehicular methanol petrol.
Along with the deep development of China reform and opening-up, national economy is held speed with 7～8% speed and increase every year, and living standards of the people improve constantly.Therefore, owing to the desirability of developping production and people's purchasing power improves, China's automobile has total amount constantly to be increased.To 1999 the year end China had 154.94 ten thousand in automobile (not containing other power car), but also increase progressively in amplification with annual 11%.Motor vehicle exhaust causes severe contamination to environment, has brought great harm to people ' s health.Especially even more serious in this pollution in densely populated big or middle city.
At this situation, country is after nineteen eighty-two has been formulated first automobile blowdown rules, formulated new vehicle pollution exhaust criteria in 2000 again, requirement reduces by 80% again with the amount of pollutant of motor vehicle exhaust, reach Europe last century Mo controlled levels (being europe I standard), realize this goal, must be improved from automobile and two aspects of gasoline.The automobile of new production should have tail gas catalytic purification system, and gasoline itself also requires perfect combustion to greatest extent, makes to generate CO
2And H
2O, and hazardous and noxious substances such as nitride, sulfide should be lacked as best one can.This will improve the quality of gasoline as early as possible.
In recent years, the development of Vehicular methanol petrol is very active, but its performance all is not very good.
The objective of the invention is for people provide a kind of methanol content big, the octane value height, long-term storage is not stratified, burning fully, engine can quick powerful speed-raising when opening the throttle, and the discharging tail gas pollution is few, is easy to perfect combustion and generates CO
2And H
2O, and the few Vehicular methanol petrols of hazardous and noxious substances such as nitride, sulfide.
The objective of the invention is to realize by following technical proposals.
Vehicular methanol petrol of the present invention, its technical characterictic is:
A) weight ratio of methyl alcohol and gasoline is that alcohol oil rate is 3/7～7/3;
B) any one among adding solubility promoter TB (alkyl phosphate) and the IBA (isomery alcohol) in methanol gasoline, its add-on is 0.005～0.01% of a total amount;
C) add ignition dope in methanol gasoline, ignition dope is an organometallic compound, and its add-on is 0.001～0.005% of a total amount.
In the such scheme, the blending process of Vehicular methanol petrol is, adds methyl alcohol earlier in material-compound tank, adds solubility promoter then, stirs to add ignition dope down, adds gasoline at last; Or add gasoline earlier, and add solubility promoter then, stir adding ignition dope down, add methyl alcohol at last; Stirred 0.5～1 hour down in 5～40 ℃ again, get Vehicular methanol petrol.
In the such scheme, described solubility promoter TB is: R
3PO
4, wherein, R is positive structure or the isomery alkyl of C4～C6.
In the such scheme, described solubility promoter TB is: tri-tert phosphoric acid ester, three amyl group phosphoric acid ester, three hexyl phosphoric acid ester.
In the such scheme, described solubility promoter IBA is: i-ROH, R are the isomery alkyl of C3～C7.
In the such scheme, described solubility promoter IBA is: Virahol, isopropylcarbinol, primary isoamyl alcohol, isohexyl alcohol, iso-heptanol.
In the such scheme, described ignition dope organometallic compound is: MR
2, wherein, R is the cyclic olefin of C4～C7, M is a transition metal.
In the such scheme, described ignition dope organometallic compound is: Dicyclopentadiene (DCPD) iron, dicyclopentadienylnickel, Dicyclopentadiene (DCPD) palladium, two cyclohexadiene iron, two cyclohexadiene nickel, two cyclohexadiene palladiums, bicycloheptadiene iron, bicycloheptadiene nickel, bicycloheptadiene palladium.
The present invention is the technical scheme that the science practicality of developing repeatedly by long-term practice is gone in invention, compared with prior art, has many advantages:
Octane value height: 95; Blowdown is low: CO:0.05～2.86%, HC:2～70PPM; Cold-resistant heat-resistant stability is good :-25～55 ℃, 5h dissolves each other not stratified.Other physical and chemical performance of Vehicular methanol petrol reaches the quality index of GB17930-1999 standard comprehensively.Product of the present invention is the motor spirit of a kind of economy type (same mileage is saved oil money about 20%), adds micro-organometallic compound and can promote burning fully, make motor quick powerful speed-raising when opening the throttle, and the discharging tail gas pollution reduces.
Below, further describing the present invention by embodiment, the present invention is not limited only to described embodiment.
