Abstract
The invention discloses an alcohol ether fuel. The alcohol ether fuel comprises the following raw material components in percentage by weight: 86-91 % of methanol, 5-10 % of ethyl ether-dimethyl ether, 0.1-0.6 % of isopropanol, 0.4-0.9 % of n-butyl alcohol or isobutyl alcohol, 0.35-0.9 % of diethyl carbonate, 0.3-0.6 % of ethyl acetate and 0.4-1.0 % of methyl tert-butyl ether. The alcohol ether fuel disclosed by the invention can be singly used as gasoline alternative fuel; and compared with the traditional 93# vehicle gasoline, the alcohol ether fuel disclosed by the invention has the advantages of excellent dynamic performance, capability of keeping stability under the low temperature condition of -40 DEG C and super-strong water resistance.
Description
Technical field
The present invention relates to alcohol-ether fuel and preparation method thereof
Background technology
The data presentation that Ministry of Industry and Information announces on August in this year 2, the external interdependency of crude oil in China reaches 55.2%, has surmounted the U.S., and this is after the external interdependency of crude oil in China is broken historical record year after year, surpasses the U.S. first.China's oil consumption speedup has surpassed the GDP speedup at present, and the energy expenditure speedup is too fast, all brings immense pressure for Energy production and energy-saving and emission-reduction.Improve China's energy structure, it is very urgent to seek new cleaning substitute energy.
Current, can substitute the product of oil, at first to measure big, one-tenth scale, secondly be that raw material is wanted fully to weigh from this point, the most qualified is exactly alcohol-ether fuel (methanol fuel and dimethyl ether fuel).It is the economical liquid fuel that can do the scale operation of raw material with coal and Sweet natural gas etc., and mature production technology stores easy to use.U.S. Nobel chemistry Prize winner, famous organic chemist George A Aura is said, " cross over the oil gas epoch, methyl alcohol economy will promote the world energy sources revolution ".Member of Chinese Academy of Engineering professor Ni Weidou points out, " dme economy is the great key that solves Chinese energy and environmental problem ".
Alcohol-ether fuel has lot of advantages as substitute energy: the one, and the wide material sources of methyl alcohol, wherein coal system methyl alcohol has more significant meaning, especially to high, the unsuitable civilian or industrial coal of sulphur content, does not also influence production methyl alcohol.From coal system methyl alcohol, also can in the multiple material of lighting, extract alcohol mixture, again with the methyl alcohol gasoline replacing that acts as a fuel, equal automobile and burn coal.The 2nd, the alcohol ether gasoline oxygen level is high, and sufficient combustion can effectively reduce and reduce discharge of harmful gases; According to national standard, oxycarbide descends 98.9%, and hydrocarbon polymer descends 88.11%; Reach EUROIII Emission Standard; Part reaches Europe IV standard, helps environment protection, the title of intrinsic environmental protection fuel.The 3rd, because of having good burning performance of alcohol-ether fuel; Can effectively eliminate the carbon deposit at each position of firing system; Avoided causing phenomenons such as power descends, burning is insufficient because of the formation of carbon deposit; And can reduce each operating mode exhaust temperature, help reducing part heat load, prolong the work-ing life of engine parts.The 4th, because methyl alcohol is a kind of solvent of excellent property in the alcohol ether gasoline; Can eliminate fuel tank and oil piping system contamination precipitation effectively and condense; Good oil circuit mediation effect is arranged, reduce cleaning mediation oil piping system and the expenses of the additives such as, fuel oil essence logical bought like oil circuit.The 5th, because use no matter alcohol ether gasoline is any a petrol engine of EFI formula and carburettor, need not do any transformation and can normally use.The 6th because the alcohol ether gasoline octane value is high, and power is strong, is applicable to high compression engine, can improve the efficient of mover, reduces oil consumption.
Fast development of Chinese economy is for alcohol-ether fuel provides great demand.China is oil consumption big country, greatly develops alcohol-ether fuel, fundamentally solves the energy problem of China, creates more social benefit, meets current socio-economic development needs, and strategic importance is great.The alcohol-ether fuel novel energy is listed " national medium-to long-range program for scientific and technological development " in, becomes the focus of people's research and development.
The kind of vehicle alcohol ether fuel of the prior art is a lot, and the standard of national alcohol-ether fuel gasoline is issued and implemented, but still has following situation:
One of which, low-temperature condition or chance regimen condition issue looks separates, and influences quality product.
Two, the vp of methyl alcohol sharply rises with the rising of temperature, is prone to cause in automobile oil transportation Lu Zhonghui appearance " gas is stifled " phenomenon.
" mix burning " three, at high proportion and have the phenomenon that is short of power.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the existing alcohol-ether fuel technology, a kind of novel vehicle alcohol ether fuel is provided.Utilize vehicle alcohol ether fuel of the present invention to reach the reduction noxious gas emission, change combustionproperty and object of energy saving.
The technical scheme that the alcohol-ether fuel invention is provided is: a kind of alcohol-ether fuel comprises the composition that weight fraction is following respectively:
Wherein the weight percent of methyl alcohol is 88%;
Wherein the weight percent of ether or dme is 7%-8%;
The preparation method: above-mentioned raw materials in proportion in pressurized vessel uniform mixing be pressed into that slaking promptly got in 24 hours in the normal temperature and pressure oil tank.
Beneficial effect (product technology advantage):
This alcohol ether gasoline: alternative to gasoline uses separately as motor spirit.
Below further set forth the present invention in detail, but do not constitute restriction protection domain of the present invention through embodiment and test.
