The characteristic of preparation is: including following steps: (1) Fatty acid ester is added in alcohol pro rate at common temperature and normal pressure, mixed uniformly, producing denatured fuel alcohol;(2) Denatured fuel alcohol and commodity signed petrol are mixed pro rate, then forming Spirits petrol.
Description
Technical field the present invention relates to a kind of fuel, particularly a kind of alcohol kind blended gasoline of being made up of pure and mild commercial labeled gasoline and preparation method thereof.
Background technology is exhausted day by day at petroleum resources, under the situation that whole world oil price rises suddenly and sharply, threatened the energy security of China, the home and abroad, develop substitute energy energetically and become a kind of irresistible trend, aspect motor spirit, study at present and use more alternative fuel that ethanol petrol and methanol gasoline are arranged, the E10 ethanol petrol is now being promoted the use of on ground such as China northeast, Shanxi, the M15 methanol gasoline is being promoted the use of on ground such as Shaanxi, E10 gasoline must use the higher dehydrated alcohol of price, thereby need state revenue and expenditure subsidy to tie up to continue, this has just greatly limited promoting the use of this abrasive fuel of ethanol petrol, more can't improve the ratio that alcohols adds gasoline, because the latent heat of vaporization of ethanol or methyl alcohol is big, the phenomenon of cold start-up difficulty takes place in the winter time easily.Chinese invention patent was on September 7th, 2005 in open day, and publication number is CN 1664078A, and invention and created name is " a kind of alcohol gasoline and preparation method thereof ", discloses a kind of alcohol gasoline, and its weak point is to contain benzene, is difficult to reach environmental protection requirement.In addition, present disclosed alcohol gasoline is in order to solve the compatibility of alcohols and gasoline, all contain emulsifying agent, and adopt is OP class, Tweens, this dish class emulsifying agent the most widely, the mentioned emulsifier burning of can not volatilizing, form easily colloid, influence the stability of oil product, cause faults such as carbon on engine or oil circuit be not smooth.Generally all contain a certain amount of free acid in the alcohols, life-time service produces corrosion to metals such as engines, reduces the work-ing life of engine.
Summary of the invention purpose of the present invention is exactly at the deficiencies in the prior art, provide a kind of cheap, can not stop up engine spray bar, non-corrosiveness, cold start-up a kind of alcohol kind blended gasoline freely and preparation method thereof.
For achieving the above object, the present invention adopts following technical scheme:
A kind of alcohol gasoline is characterized in that: mainly be made up of alcohol, commercial labeled gasoline, fatty acid ester, the weight percent of described each component is as follows:
Alcohol 18%48%
Commercial labeled gasoline 50%-80%
Fatty acid ester 0.2%-2%
Thanomin 0.001%-0.01%
The lighter hydrocarbons 0.1%-1% of C3～C4
Wherein, the concentration of described alcohol is more than 95%, and described alcohol is one or both in ethanol, the methyl alcohol.
Preferably, described concentration of ethanol is 95%～96.5%; The concentration of described methyl alcohol is more than 98%.
Preferably, described commercial labeled gasoline is the low grade commercial gasoline below No. 93 or No. 93.
Preferably, described fatty acid ester is one or more in fatty acid methyl ester, the fatty-acid ethyl ester.
Preferably, described fatty acid ester is a unsaturated fatty acid ester.
Preferably, described fatty acid ester is a fatty acid methyl ester, and its content is not less than 92%.
Preferably, described thanomin is Monoethanolamine MEA BASF, diethanolamine, trolamine, N methyldiethanol amine, dimethylethanolamine, N, one or more in the N-diethylethanolamine.
Preferably, the lighter hydrocarbons of described C3～C4 are liquefied petroleum gas (LPG).
A kind of preparation method of alcohol kind blended gasoline is characterized in that: may further comprise the steps:
(1) under the normal temperature and pressure fatty acid ester is joined in the alcohol in proportion, stir, make denatured fuel alcohol;
(2) denatured fuel alcohol is mixed with commercial labeled gasoline in proportion alcohol gasoline;
Thanomin is at normal temperatures and pressures fatty acid ester, thanomin to be joined in the alcohol in proportion in step (1), stirs, and makes denatured fuel alcohol;
C3-C4 slowly injects the C3-C4 lighter hydrocarbons in proportion in step (1), is dissolved into the fatty acid ester, thanomin, the alcohol that have mixed, makes denatured fuel alcohol.
The present invention uses micro-emulsion technology on principle, utilize the amphipathic property matter of nonionic emulsifier, water molecules and polar molecule in ethanol or the methyl alcohol are evenly dispersed in the gasoline with minimum fine-grannular, form stable transparence microemulsified liquid on the thermodynamics, this liquid does not have demixing phenomenon half a year and takes place storing more than-18 ℃.Because the nonionic emulsifier of selecting for use is a fatty acid methyl ester, itself also is a kind of high heating value material, can fully burn with gasoline, do not produce colloid, can not stop up the engine spray bar, belong to biomass energy, very be suitable as the additive of alcohol kind blended gasoline.The thanomin that the present invention uses can neutralize the free acid that produces in ethanol or the methyl alcohol, slows down and prevents corrosion of metal; And the C3-C4 lighter hydrocarbons, the vapour pressure that can regulate alcohol kind blended gasoline effectively, thereby can solve the cold start problem of alcohol kind blended gasoline in winter effectively.
A kind of alcohol kind blended gasoline of the present invention, can be mixed into stable transparent liquid with arbitrary proportion and commercial labeled gasoline, by a series of engine rig tests its performance is screened, should power strong, oil consumption is low again, also will discharge, and best price/performance ratio is defined as E30 ethanol petrol and M30 methanol gasoline, these two kinds of alcohol kind blended gasolines are through the check of China Renmin People's Liberation Army Office Support Engineering Academy's oil product inspection center, and every index all reaches the technical requirements of GB white gasoline.
The E30 ethanol petrol of the present invention's preparation, the ethanol working concentration is 95%～96.5%, and cheap about 1000 yuan per ton than dehydrated alcohol, state revenue and expenditure needn't be subsidized, and still there is profit in enterprise, and forms energy agriculture and recycling economy industrial chain easily.
The M30 methanol gasoline of the present invention's preparation, cost is lower, for the resourceful area of methyl alcohol, has increased the diversity of national substitute energy.
A kind of alcohol kind blended gasoline of the present invention, cheap, power is strong, oil consumption is low, discharge, and can not stop up the engine spray bar, non-corrosiveness does not corrode fuel tank, oil circuit and engine, stable storing, cold start-up is good.Preparation method's technology of alcohol kind blended gasoline of the present invention is simple, easy to operate.
