Abstract
The invention discloses an additive for improving the water resistance of methanol gasoline, which is prepared by mixing the following components in percentage by weight: 45-55% of C3-5 monohydric mixed alcohol, 20-30% of isobutenylamide isoheptyl ester and 25-30% of surfactant. The additive disclosed by the invention can improve the water-phase separating property of methanol gasoline, is superior to the traditional alcohol additive in water-resistant effect and can ensure that the water resistance of Chinese standard 93# gasoline is increased by 0.3% during methanol-blended combustion. The additive disclosed by the invention is low in production cost, remarkable in effect and easy to popularize.
Description
Technical field
The invention belongs to methanol fuel for vehicles technical field, relate to a kind of Vehicular methanol petrol additive, particularly a kind of additive that improves methanol gasoline water repelling property.
Background technology
Current economy develops rapidly, and the demand of the energy is increased day by day.Gasoline is one of most important Nonrenewable energy resources, because world's natural oil storage reduces year by year, impel countries in the world just actively to utilize existing resource to find the clean energy products of some alternative gasoline, methanol gasoline arises at the historic moment as most potential fuel substitute, and more and more enjoys favor.
Methyl alcohol wide material sources, not only can optimize fuel source structure, alleviate oil-fired dependence, and are chemical fertilizers production, and the enterprise of the by-product methyl alcohol such as Coal dressing brings opportunity and benefit, the more important thing is its energy-conserving and environment-protective.Therefore, development research has realistic meaning using methyl alcohol as alternative motor fuels.
Conventional methanol gasoline has M15 ﹑ M25 and M85 at present, and in order to reach GB requirement, chance water and the Di temperature Fen Ceng ﹑ Jin that need to add therein certain additive to solve fuel belong to the problems such as Fu Shi ﹑ swell rubber.Wherein, methanol gasoline is having meeting under water existence condition that phenomenon of phase separation occurs, and this directly affects production and transport and the storage of methanol gasoline.
People have carried out positive research to the water repelling property of methanol gasoline, as Wu Jianzhen etc. (the resistance Separate Efficiency Study of methanol gasoline. Liaoming Petrochemical Univ's journal, 2012,32 (2): 35-37,42.) according to the Structure Selection of methanol molecules three kinds of phase separation inhibitors, while finding by experiment additive volume fraction to be 5%, 100ml methanol gasoline dissolves the optimum addn amount of 0.3ml water.Chen Yue etc. (methanol gasoline is met the composition research of water resisting phase separation solubility promoter. contemporary chemical industry, 2011,40 (4): 380-382.) studied solubility promoter after C3～C8 alcohol the is composite improvement situation to methanol gasoline water repelling property, when mainly having studied solubility promoter and being 4%, the maximum solvable water 1.2% of M50.These researchs adopt traditional water resistant additive mostly, additive amount is large, cost is high, and high Humid Area DeGrain (Zhao Rongxiang etc. heavy oil fluid catalytic cracking tensio-active agent synthetic. Liaoming Petrochemical Univ's journal, 2009,29 (2): 34-35,38.).
Summary of the invention
The object of the present invention is to provide a kind ofly for improving the additive of methanol gasoline water repelling property, this additive has advantages of that solvability is good, addition is few.
Additive of the present invention is to be mixed by the component of following weight percent: C3～C5 monobasic mixes alcohol 45%～55%, Isocrotyl acylamide isoheptyl ester 20%～30%, tensio-active agent 25%～30%.Above-mentioned additive is added in 93# gasoline by a certain percentage with after methanol mixed, can effectively improve the water solubilization of methanol gasoline.
Wherein, described Isocrotyl acylamide isoheptyl ester is produced by Jiahong Petrochemical Science and Technology Co., Ltd., Xi'an.
The mixed alcohol of described C3～C5 monobasic is one or more the alcohol mixture of arbitrary volume ratio in n-propyl alcohol, Virahol, propyl carbinol, isopropylcarbinol, Pentyl alcohol, primary isoamyl alcohol.
Described tensio-active agent is mixed by lower surfactant by weight percentage:
Polyoxyethylene sorbitan fatty acid ester 25%～30%
Fatty alcohol-polyoxyethylene ether 40%～50%
Polyoxyethylene octylphenol ether 25%～30%.
Additive of the present invention can improve the chance aqueous phase separation performance of methanol gasoline, is better than the water resistant effect of traditional alcohols additive, and can ensure that GB 93# gasoline water repelling property in the time mixing burning methyl alcohol improves 3 ‰.By volume ratio is used 3%～5% above-mentioned additive to mix and makes methanol gasoline with the methyl alcohol of 82%～80% gasoline and 15%, and after being in harmonious proportion, fused property is good, and low temperature or meet a small amount of water and be difficult for layering is difficult for muddiness.
Additive Production cost of the present invention is low, and successful is easy to promote.
