Description
Technical field
The present invention relates to fuel chemical industry technical field, particularly relate to frigid plateau region methanol fuel additive and the methanol fuel containing this additive.
Background technology
The world today is faced with two large problems: one is petroleum-based energy crisis.World oil reserves are limited, and along with expanding economy, petroleum consumption increases just year by year.Two is environmental pollutions.When making fuel with refined oil, the health of people in the multiple carcinogenic substance serious threat contained in the hydrocarbon, hydrocarbon polymer, oxynitrides, oxygen sulfur compound and the oil that contain in the discharge gas after burning.Therefore, actively seek and develop the cardinal task that clean energy has become various countries, relative to electric energy, liquid hydrogen, liquefied petroleum gas (LPG), Sweet natural gas, nuclear energy etc.Alcohol-group fuel not only has route of synthesis by all kinds of means as new cleaning fuel, and its recycling is simultaneously significant to alleviation Global warming, and application prospect is very wide.
Based on the alcohol radical liquid fuel of fuel methanol, ethanol, it is the clean energy of a kind of cheapness, environmental protection, can be raw material production by coal, heavy oil, Sweet natural gas or biomass etc., raw material sources are wide, production technique is simple, technology maturation, medium and small nitrogen fertilizer factory in all parts of the country all can coproduction or production of changing the line of production.Produce the important component part that alcohol-group fuel is again coal liquefaction and biomass production renewable energy resources technology, the cost of scale production alcohol-group fuel, far below other clean fuels, has the extremely strong market competitiveness.If this fuel is popularized, the shortage of China's oil resource will be made up to a great extent, and the localization production and supply of clean fuel can be realized within the specific limits, to guarantee Chinese energy safety, there is extremely important strategic importance.
External methyl alcohol starts from the twenties in 20th century as fuel substitute, is successfully applied to Germany; By the impact of secondary oil crisis after the 70's of 20th century; add that surplus and the people of world methanol throughput are more and more higher to environmental quality requirement; the states such as the U.S., Japan, Germany and Sweden successively drop into the research and development that human and material resources carry out methanol fuel and methanol fuel supporting technology, achieve breakthrough progress.2006 at Germany, Austria and the methanol fuel of U.S.'s lower concentration with commercial applications, occupy its market 85%, 50% and 10%.From the eighties in 20th century, the methanol fuel of active development 50 and 85 type (interpolation per-cent) abroad.
The research of China to methanol fuel is started in the initial stage the 70's of 20th century, and methanol fuel research is in recent years advanced by leaps and bounds especially, and not only a relevant technologies difficult problem is broken through, its practical application fast development especially.On January 25th, 2003, State Economic and Trade Commission organizes the Chinese Academy of Sciences, academician of the Chinese Academy of Engineering and professor to investigate to Shanxi fuel methanol project, demonstrates fuel methanol as a kind of alternative fuel, has become irreversible development trend.At present, there are thousands of nitrogen fertilizer plants in the whole nation, combined production of methanol device has been had in many producers, add per unit area yield methanol device, the yearly capacity of the methyl alcohol product installation that China has been constructed and put into operation is at about 5,000,000 tons, among the device of more than 400 ten thousand tons/year is being built in addition, the market supply of alcohol-group fuel has had reliable guarantee, can meet the market demand of alcohol-group fuel completely widely.
1996, State Bureau of Technical Supervision promulgated GB 16663-1996 " alcohol radical liquid fuel " national standard; 1997, National agricultural cloth promulgated by the ministries or commissions of the Central Government N Y 312-l997 " alcohol civil fuel kitchen range " industry standard.The promulgation of these 2 standards is to specification alcohol-group fuel and promote that the development of this industry has great effect.Current large-proportion methanol combustion technology has captured that methyl alcohol calorific value low dynamics is not enough, cold starting is difficult, hot gas resistance, meet seven hang-ups such as water stratification, poor stability, corrosion are swelling, high temperature lubricating, makes China's methanol fuel state of the art reach prostatitis, the world.
But existing methanol fuel is easier layering under high altitude anoxia low pressure and cold condition, all there is dynamic property deficiency, incendivity not exclusively waits not enough.
