Abstract

The present invention relates to a kind of synthetic gasoline, it is made up of methyl alcohol, gasoline, solvent oil, rosin, acetone, isopropylcarbinol and dimethylbenzene, it has solved existing is the low problem of addition content of methyl alcohol in the synthetic gasoline of main raw material with methyl alcohol, makes the addition content of methyl alcohol be up to 80%.It is easy to use, prepare and can use, and it is extensive to have raw material sources, and cost is low, and handiness is good, and it is big to urge power, quicken and grade climbing performance good, series of advantages such as start easily, and be not subjected to the weather condition restriction, the four seasons all can produce.And can use, lower by 1～4% than gasoline mileage oil consumption, and tail gas meets the emission standard of environmental protection requirement. throughout the year

Description

Synthetic gasoline

The present invention relates to a kind of automobile-used fuel substitute, particularly a kind of synthetic gasoline.

Along with development and national economy, the imbalance between supply and demand of gasoline is increasing, and the par petrol delivery amount of planned supply can not be satisfied the demand far away, and the user has to engross agreed-upon price gasoline from market to be higher than the price of par gasoline more than one times, thereby increased cost, reduced economic benefit.Simultaneously, owing to gasoline extract from oil, and reserves is always limited, so, seek new automobile-used fuel substitute, have crucial meaning.

In a large amount of automobile-used fuel substitutes, using more, development is exactly methanol gasoline faster, and it is to be spiked in the motor spirit to replace commercial labeled gasoline as gasoline vehicle fuel with part methyl alcohol.Because methyl alcohol and gasoline intermiscibility are poor, need to add certain quantity of additive and make methyl alcohol and gasoline miscible and reach homogeneous phase.Simultaneously, some additive improves the effect of anti-knocking property and increase gasoline octane rating in addition.

Additive commonly used has methyl tert butyl ether, is called for short the mixed alcohol of MTBE and 04-08 again.Yet MTBE is with the iso-butylene synthetic in the oil gas, because the shortage of iso-butylene, MTBE is difficult to a large amount of synthetic.As for mixing alcohol, synthetic at present mixed pure technology does not still pass a test, and from grain distillery's fermentation system alcoholic acid by product, wherein the output of 04-08 alcohol is limited, has also limited the production in enormous quantities of methanol gasoline as additive mostly for mixed alcohol.Simultaneously, the addition content of methyl alcohol is not high yet, generally only is

In order to address the above problem, Chinese patent CN 86104230A discloses a kind of gasoline with high carbinol content, it adopts Methylal(dimethoxymethane) as the methanol vapor oil additives, be aided with a spot of lower boiling gasoline, aromatic hydrocarbons and lipid acid, thereby improved the addition content of methyl alcohol greatly, simultaneously, reduced the cost of additive, its raw material sources (Methylal(dimethoxymethane) is be that the Chemicals-methyl alcohol of raw material and formaldehyde are synthetic come) have been enlarged with the resource abundant in coal, make the large-scale application methanol gasoline become possibility, but still there is following weak point in it:

One, uses inconvenience

1, must be equipped with the oily machine compatibility of adjustment can use.

2, must do some transformation to adapt to the application of gasoline with high carbinol content to petrol engine.

3, must adjust the ignition angle of engine.

4, must be with the floater of foam in the copper float replacing EQ140 gasoline car carburettor.

5, must adjust the Zhang Du of acceleration pump heifer bowl support spring circle in the gasoline engine carburetor.

Two, the addition content of methyl alcohol still lower (only being 50～65%)

The objective of the invention is provides a kind of easy to use in order to overcome the above problems, and does not need available engine is made any change and the higher synthetic gasoline of allotment addition content just that can directly use, methyl alcohol.

Realize that embodiment of the present invention is: synthetic gasoline is a major ingredient with methyl alcohol and gasoline, adopts solvent oil, rosin, acetone, isopropylcarbinol and dimethylbenzene to make additive.Acetone, dimethylbenzene and isopropylcarbinol have raising rate alkane value and combustion-supporting effect, in order to improve the speed of a motor vehicle, have lubricating function, prevent component wear.In addition, acetone, isopropylcarbinol make the limpid transparent function of color and luster of synthetic gasoline in addition.The effect that methyl alcohol, rosin, solvent oil and gasoline have is combustion-supporting, improve the speed of a motor vehicle and explosive power.

The emphasis per-cent of each component of synthetic gasoline is: methyl alcohol 25～85%, gasoline 10～40%, solvent oil 5～35%, rosin 1～10%, acetone 1～6%, isopropylcarbinol 1～4%, dimethylbenzene 1～10%.

The present invention is owing to adopt as above prescription; improved the addition content (reaching as high as 80%) of methyl alcohol; easy to use, the preparation back can be used at once, does not need original engine is done any change and adjustment; synthesis technique is simple; and not limited by weather, the four seasons all can produce, and can use throughout the year; prove through test of many times; it is good to have handiness; it is big to urge power; quicken and grade climbing performance good, series of advantages such as start easily, color and luster is limpid transparent; not stratified; there is not saturated group, lower by 1～4% than gasoline mileage oil consumption, and benzene content is low; unleaded; so the waste gas after burning environmental pollution is few, meet the emission standard of environmental protection requirement.Through 608 repeatedly tests of Ministry of Astronautics Industry, meet SY1004-65 RQ-80 gasoline standard.

Specifically introduce several prescription of the present invention below in conjunction with embodiment:
