Abstract

The invention relates to fuel and in particular relates to high-ratio methanol gasoline. The high-ratio methanol gasoline is used for a high-compression-ratio vehicle by adding a trace amount of a bio-additive and a modifier into the gasoline under the circumstance that the methanol content is not less than 70%, and gasoline 93#, 97# and 98# can be directly replaced without modifying an engine; phase separation cannot occur under the circumstance that the water content of the high-ratio methanol is 3%; the engine can be normally started and can normally work under the circumstance that the extreme temperature is minus 30 DEG C; the high-ratio methanol gasoline can be soluble with the vehicle gasoline 93#, 97# and 98# at any ratio; carbon monoxide and hydrocarbon compounds emitted by tail gas generated by using the high-ratio methanol gasoline are reduced by more than 80% in comparison with those emitted by tail gas generated by using the gasoline; when the high-ratio methanol gasoline is used in hot summer, the 'gas blockage' phenomenon of the oil way of the vehicle cannot be caused; the additive amount of the required additive is low, the effect is good, the cost is low, and good economic and social benefits can be achieved.

Description

A kind of gasoline of high proportion methanol

The present invention relates to fuel-based, specifically relate to a kind of gasoline of high proportion methanol.

Along with the economic fast development in the world, further powerful to the demand of the energy, particularly domestic economy is at status and the fast-developing needs in the world, just more urgent to the demand of the energy.The Energy Situation of China, the energy fuel that is petroleum-type is deficient, so the substitute energy of the fuel of development petroleum-type is needs and the demand of current national energy development strategy, as the corrodibility of your material, swelling property, vapour lock, power reduce, meet many technical barriers such as water stratification, cold start-up difficulty.

Order of the present invention ground is according to above-mentioned prior art weak point, a kind of gasoline of high proportion methanol is provided, in this gasoline in the situation that the content of methyl alcohol is not less than 70%, by adding after micro-biotic additives and micro-properties-correcting agent, when thoroughly solving the problem of above-mentioned prior art existence, optimizing product quality.

Order of the present invention ground is realized by technical scheme once and being completed:

A kind of gasoline of high proportion methanol, comprise 90# gasoline, it is characterized in that, in the proportioning of this methanol gasoline, the content of methyl alcohol is 70-95%, wherein also contain the stablizer of 1%-3%, what described stablizer adopted is biotic additives, and this biotic additives is the alcohols that bio-oil after chemical reaction generates.Take methanol content 85% as the most frequently used.

Biotic additives can be that bio-oil is through the alcohols of the chemical reaction generation of over hydrogenation.This alcohols is the mixture of C8-C18 fatty alcohol.

Biotic additives can be also that bio-oil is through the alcohols of the chemical reaction generation of over-churning and hydrogenation.This alcohols is the mixture of C12-C14 fatty alcohol.

In the proportioning of described methanol gasoline, also be added with 1.5 ‰-8 ‰ properties-correcting agent, its component is in every 100 parts, each component accounts for respectively: methyl alcohol 9.5-14 part, ethanol 13-19 part, 2,6 di-t-butyl mixed phenol 1.5-2.5 parts, dialkyl group 2,6 generation phosphoric acid zinc salt 0.95-1.5 part, toluene 1.8-2.8 part, phenylcarbinol 6-9 part, methyl ethyl diketone 0.6-1 part, ethyl acetate 1.2-1.8 part, Methylal(dimethoxymethane) 6.5-9.5 part, Skellysolve A 4.5-7 part, acetone 9.6-14 part, 97# gasoline 14.5-21.5 part, secondary octanol 11-16 part, oily public ignition dope 1-3 part.

Advantage of the present invention is, on high compression ratio automobile, uses, and without changing engine, can directly replace GB 93#, 97#, 98# gasoline to use; The in the situation that of there is 3% water in product, be not separated; In ℃ situation of extreme temperature-30, engine can normal starting, normally work; Product of the present invention can dissolve each other with international 93#, 97#, 98# motor spirit in any proportion; Use product of the present invention, quantity discharged when exhaust emissions carbon monoxide, hydrocarbon polymer ratio are used gasoline will reduce more than 80%; At hot summer weather, using, can there is not " gas is stifled " phenomenon in automobile oil-way; The addition of additive required for the present invention is few, effective, and cost is low.

By the following examples feature of the present invention and other features are described in further detail, so that technician's of the same trade understanding:

What the present embodiment related to is M85 Vehicular methanol petrol, and its proportioning is:

Methyl alcohol 85%, stablizer 2%, methanol gasoline properties-correcting agent 5 ‰,, all the other compositions are 90# gasoline, the concentration of methyl alcohol is more than 99.5%.

This stablizer can adopt the mixture of C8-C18 fatty alcohol, its preparation method be by bio-oil for example Viscotrol C or Semen Maydis oil, under catalyst action, hydrocracking, then through dehydration and distillation cutting process, remove fusel, obtain the mixture of C8-C18 fatty alcohol.

This stablizer can also adopt the mixture of C12-C14 fatty alcohol, its preparation method is by bio-oil for example Viscotrol C or Semen Maydis oil and methyl alcohol, process normal temperature and pressure transesterification reaction under the katalysis of sodium methylate, pass through again hydrogenation distillation process, obtain the mixture of C12-C14 fatty alcohol, adopt the stablizer of this component, result of use is better than adopting the mixture of C8-C18 fatty alcohol.

The effect of stablizer is the vapour pressure that reduces gasoline of high proportion methanol, gasoline of high proportion methanol, its vapour pressure increases with temperature and rises very soon, and the vapour pressure of stablizer is relatively much lower, its temperature profile increases severely unlike methanol gasoline, thereby the methanol gasoline vapour pressure after hybrid reaction is reduced under same temperature, stoped gas stifled.

This methanol gasoline properties-correcting agent: can play cylinder body protection, antioxygen, inhibition, improve the effects such as starting characteristic.Its component is in every 100 parts, each component accounts for respectively: 16 parts of 12 parts of methyl alcohol, ethanol, 2,2 parts of 6-di-t-butyl mixed phenols, dialkyl group 2,6 generation 1.2 parts of phosphoric acid zinc salts, 2.3 parts of toluene, 7.5 parts of phenylcarbinols, 0.8 part of methyl ethyl diketone, 1.5 parts of ethyl acetate, 8 parts of Methylal(dimethoxymethane), 6 parts of Skellysolve As, 12 parts, acetone, 18 parts, 97# gasoline, 13.7 parts of secondary octanols, oily public ignition dope 1-3 part.

This properties-correcting agent in use, can, according to the variation of the different qualities of methyl alcohol and gasoline and working conditions, be adjusted the wherein share of each component.

In the identical situation of other conditions (characteristic and the working conditions that comprise methyl alcohol and gasoline), along with methyl alcohol proportion is when the inner conversion of 70%-95% scope, the adding proportion of its stablizer and methanol gasoline properties-correcting agent does not have too many difference, the variation of its adding proportion is main relevant with characteristic and the working conditions of methyl alcohol and gasoline, and wherein working conditions comprises vehicle condition etc.

Those skilled in the art are obviously appreciated that in the present invention for the selection of 90# gasoline, can also substitute with petroleum base light oil, within these contents should belong to protection domain of the present invention.
