Description
Technical field
The present invention relates to a kind of alcohols fuel substitute field, particularly a kind of based on biomass energy, kinetic enhancers of biological alcohols and preparation method thereof can be admixed at high proportion.
Background technology
For a long time, the fuel of all kinds of motor vehicle is always based on gasoline, diesel oil, and this using forestland is more and more subject to the restriction that environmental pollution is serious and resource is day by day in short supply.In order to improve this predicament, have employed various energy resources alternative both at home and abroad, but these alternative, to large-scale promotion, all also exist serious defect.In recent years, because international oil price continues to spiral in a high position, accelerate speed of applying and the flow of research of domestic and international substituting alcohol-ether fuel.Clean as one, cheap, the efficient gasoline substitute of alcohol gasoline, comes into one's own with the source that it is abundant, is considered to most promising alternative motor fuels.For this reason, the research that a large amount of man power and materials carries out alcohol gasoline has all been dropped in countries in the world.The enforcement of Strategic Policy can be replaced according to the energy of National Development and Reform Committee's promulgation, and the promulgation of methanol gasoline standard, methanol gasoline is legalized further, impels people to start to test the various additives of alcohol gasoline.But technically, the biggest problem of restriction methanol gasoline is that the calorific value of methyl alcohol is low, affects the power of motor car engine, which limits mixing at high proportion of methyl alcohol.The calorific value of gasoline is 44.37MJ/kg, and the calorific value of methyl alcohol is only 20.09MJ/kg, only has 45% of gasoline.Therefore, after adding methyl alcohol in gasoline, its propellant combination low heat value linearly declines.Power and the moment of torsion of engine will be obviously reduced when methanol ratio increases.Thus solve that methanol gasoline heat value is low, to be short of power be promote the great difficult problem of Aalcohols fuel.Alcohols hydrotropy is cold to be opened, high temperature vapour lock, meet water stratification, metallic corrosion, swell rubber, peat deposits, oleyl alcohol are stablized is affect the reason that Aalcohols fuel is obstructed, to not equal to methanol gasoline low heat value, be short of power the most the underlying cause being only and causing Aalcohols fuel to be obstructed, significantly to have some idea of.
In order to solve methanol gasoline low heat value, being short of power etc. affects methanol gasoline fundamentally, the achievement patent occurred in recent years can be said at most, is really " each one showing his or her special prowess ".A large amount of patents, in order to improve power, increase octane value, is all adopt MTBE, trimethyl carbinol limiting reagent to realize, as CN101906329A, CN101851534A, CN101886004A and CN101705122A etc.; Adopt all kinds of catalysis process in addition, as fuel catalyst in CN101619250A and heat value agent nitrate, carbonate, draw agent halogenide, limit popularization and the use of alcohol gasoline; Some calorific value catalyzer employs heavy metallic salt, routine CN102146304A (KNO
3), CN101029258A (KMnO
4), CN101343574A (ferrocene), CN101372636A (MMT); In CN101985569A, CN101643673A, its power promotor is the nitro-compound such as nitric ether, oil of mirbane, and these reagent all will cause the aggravation of electrochemical reaction; Employ coal tar and anhydrous hydrazine in CN101724471A, CN102260548A power promotor, although create positively effect to power, coal tar can make the combustioncharacteristics of gasoline be deteriorated, and anhydrous hydrazine severe toxicity, is added in methanol gasoline and is harmful to human and environment; In CN101343574A, CN101724474A, calorific value synergistic agent is tetrahydrofuran (THF), hydroxyquinoline is to increase calorific value and improve engine power and play an important role, but these are all belong to expensive fine chemicals, and cost is higher.
Summary of the invention
