Description
Technical field
The present invention relates to alcohol ether diesel 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 first the U.S..China's oil consumption speedup has surpassed the GDP speedup at present, and the energy expenditure speedup is too fast, all brings immense pressure to Energy production and energy-saving and emission-reduction.Improve China's energy structure, seek new clean substitute energy very urgent.
Current, product that can petroleum replacing, at first will measure greatly, on a large scale, is secondly that raw material is wanted fully, from this point, to weigh, and the most qualified is exactly alcohol-ether fuel (methanol fuel and dimethyl ether fuel).It is to make the economical liquid fuel of the scale operation of raw material with coal and Sweet natural gas etc., and mature production technology, store 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 China energy and environmental problem ".
The alcohol-ether fuel energy as an alternative has lot of advantages: the one, and the wide material sources of methyl alcohol, wherein coal methyl alcohol processed has more great meaning, and especially high to sulphur content, unsuitable civilian or industrial coal, do not affect methanol yet.From coal methyl alcohol processed, also can in the multiple material of lighting, extract alcohol mixture, then, by the methyl alcohol replacement gasoline that acts as a fuel, equal automobile and burn coal.The 2nd, the alcohol ether gasoline oxygen level is high; sufficient combustion; can effectively reduce and reduce the discharge of obnoxious flavour; according to national standard, oxycarbide descends 98.9%, and hydrocarbon polymer descends 88.11%; reach EUROIII Emission Standard; part reaches Europe IV standard, is conducive to 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 formation because of carbon deposit to cause the power phenomenon such as insufficient that descends, burns, and can reduce each operating mode exhaust temperature, be conducive to reduce part heat load, extend the work-ing life of engine parts.The 4th, because in alcohol ether gasoline, methyl alcohol is a kind of solvent of excellent property, can effectively eliminate fuel tank and oil piping system contamination precipitation and condense, good oil circuit dredging effect is arranged, reduce the clean expenses as additives such as oil circuit are logical, fuel oil is smart of dredging oil piping system and buying.The 5th, because use no matter alcohol ether gasoline is any a petrol engine of electric spray type 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 efficiency of engine, reduces oil consumption.
The fast development of China's economic, for alcohol-ether fuel provides the huge market requirement.China is oil consumption big country, greatly develops alcohol-ether fuel, fundamentally solves Chinese energy problem, 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 diesel is issued and implemented,
(1) flash-point, cetane value are lower than basic diesel oil
(2) the high layoutprocedure complexity of solubility promoter price
(3) emulsifying water of unstable properties chance can not be mixed with pure diesel oil
Summary of the invention
The object of the invention is to overcome the deficiency existed in existing alcohol ether diesel technology, a kind of novel alcohol ether diesel oil for vehicles is provided.Utilize alcohol ether diesel oil for vehicles of the present invention to reach the reduction noxious gas emission, change the purpose of combustionproperty and energy efficiency.
The technical scheme that the alcohol ether diesel invention provides is: a kind of alcohol ether diesel, comprise diesel oil 0～60%, and alcohol-ether fuel 40～100% is characterized in that: alcohol-ether fuel comprises the following material composition of weight fraction difference:
The preparation method: above-mentioned raw materials in proportion in pressurized vessel homogenious charge compression enter in the normal temperature and pressure oil tank slaking 24 hours and get final product.
Beneficial effect (product technology advantage):
First: without the transformation engine, can with petrifaction diesel arbitrarily than, 10～30% dissolve each other, also can be used alone, do not affect engine operation, dynamic property, oil consumption and petrifaction diesel are suitable.
Second; Additive used is the general chemical raw material, and source is easy to get, and the alcohol ether diesel outward appearance is limpid transparent.
The 3rd: alcohol ether diesel good stability of the present invention, water resisting property is strong, and effectively solve methanol diesel-oil and met emulsifying water, the cold-starting difficulty, the high temperature vapour lock, methyl alcohol is to corrosion of metal and the swelling of checking rubber, and methanol ratio hangs down and waits technical barrier.
The 4th: alcohol ether diesel oxygen level of the present invention is high, and sufficient combustion can effectively reduce and reduce noxious gas emission, and be conducive to environment protection and improve the ecological environment, be environmental protection fuel.
Reach by the following examples test and further elaborate the present invention, but do not form limiting the scope of the invention.
