Description

Gasoline of high proportion methanol

Technical field

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

Background technology

The kind of present gasoline of high proportion methanol of the prior art is a lot, but exist the common defective be to need to change motor car engine, reason be at first methyl alcohol to the corrodibility of automobile Material Used, and to the swelling of the pipeline of fuel transfer system, sealing member, service station's respective material, in addition at internal characteristic, the external characteristics of petrol motor, because methanol gasoline heat value is gasoline half, and the calorific value of air gas mixture approaches gasoline mixture.Also there is following situation in methanol gasoline, one, chance aqueous phase separation, and the water that general existing product can only control to 0.5%-1% is not separated; Be that the applied environment temperature can influence and is separated two,, common product controls to-25 ℃ and is not separated, this winter northern area be unconformable.Though the vapour pressure of methyl alcohol is forced down than the steam of gasoline in addition, but rising with temperature, its vapour pressure sharply rises, easily cause in the oil delivering pipe of car road, occurring " gas is stifled " phenomenon, especially in summer and south, so effectively reduce the vapour pressure of gasoline of high proportion methanol, be to guarantee a very important aspect of the normal operation of gasoline of high proportion methanol car.

Summary of the invention

The objective of the invention is according to above-mentioned the deficiencies in the prior art part, a kind of gasoline of high proportion methanol is provided, in this gasoline under the content of methyl alcohol is not less than 70% situation, after adding micro-biotic additives and micro-properties-correcting agent, when thoroughly solving the problem of above-mentioned prior art existence, optimize product quality.

The object of the invention realizes being finished by following technical scheme:

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

Biotic additives can be the alcohols that bio-oil generates through the hydrogenant chemical reaction.This alcohols is the mixture of C8-C18 Fatty Alcohol(C12-C14 and C12-C18).

Biotic additives also can be the alcohols of bio-oil through over-churning and the generation of hydrogenant chemical reaction.This alcohols is the mixture of C12-C14 Fatty Alcohol(C12-C14 and C12-C18).

In the proportioning of described methanol gasoline, also be added with 1.5 ‰-8 ‰ properties-correcting agent, its component is in per 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 part, 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.

Advantage of the present invention is, uses on the high compression ratio automobile, need not to change engine, can directly substitute GB 93 ^#, 97 ^#, 98 ^#Gasoline uses; In product, exist under the situation of 3% water, be not separated; Under extreme temperature-30 ℃ situation, but engine normal starting, works better; Product of the present invention can be by arbitrary proportion and international 93 ^#, 97 ^#, 98 ^#Motor spirit dissolves each other; Use product of the present invention, exhaust emissions carbon monoxide, the quantity discharged when the hydrocarbon polymer ratio uses gasoline will reduce more than 80%; Use at the hot summer weather, " gas is stifled " phenomenon can not take place in the automobile oil circuit; The addition of additive required for the present invention is few, and is effective, and cost is low.

Embodiment

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

What present embodiment related to is the 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(C12-C14 and C12-C18), and its preparation method is with bio-oil for example Viscotrol C or Semen Maydis oil, under catalyst action, hydrocracking, through dehydration and distillation cutting process, remove fusel again, obtain the mixture of C8-C18 Fatty Alcohol(C12-C14 and C12-C18).

This stablizer can also adopt the mixture of C12-C14 Fatty Alcohol(C12-C14 and C12-C18), its preparation method is with 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 the hydrogenation distillation process again, obtain the mixture of C12-C14 Fatty Alcohol(C12-C14 and C12-C18), adopt the stablizer of this component, result of use is better than the mixture that adopts the C8-C18 Fatty Alcohol(C12-C14 and C12-C18).

Function of stabilizer is to reduce the vapour pressure of gasoline of high proportion methanol, gasoline of high proportion methanol, its vapour pressure increases and very fast rising with temperature, and the vapour pressure of stablizer is much lower relatively, its temperature profile increases severely unlike methanol gasoline, thereby the methanol gasoline vapour pressure after the hybrid reaction is reduced under same temperature, stoped gas stifled.

This methanol gasoline properties-correcting agent: can play cylinder body protection, antioxygen, inhibition, improve effects such as starting characteristic.Its component is in per 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, 1.2 parts of dialkyl group 2,6 generation 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 in acetone, 18 parts in 97# gasoline, 13.7 parts of secondary octanols.

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

Under the identical situation of other conditions (characteristic and the working conditions that comprise methyl alcohol and gasoline), along with the proportion of methyl alcohol 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 the characteristic and the working conditions of methyl alcohol and gasoline, and wherein working conditions comprises vehicle condition etc.

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