Background technology
The a large amount of SO that produce in sulfur-containing compound combustion process in fuel oil (gasoline or diesel oil)x, be to form acid rain, causeThe one of the main reasons of environmental pollution on a large scale, the mankind's health and the ecological balance of the earth in serious threat. Countries in the world pairIn fuel oil, the requirement of sulfur content is more and more stricter; At present, although the hydro desulfurization of industrial extensive employing can effectively removeInorganic sulfur in fuel oil and part organic sulfur, but to substituent thiophene, benzothiophene, dibenzothiophenes and other thiopheneThe desulfuration efficiency of derivative is but very low; For this reason, each state has all strengthened the research to other degree of depth process for sulfur removal, as oxidation sweeteningMethod, liquid-phase extraction method, direct absorption method, biological desulphurization method etc., wherein, oxidation sweetening method is acknowledged as one prospect very muchDesulfur technology; But, this method realize in industrialized process, still exist a lot of difficulties, especially oxidant cost andThe design of high activated catalyst also fails to be solved at all, therefore, the key of oxidation sweetening method be exploitation a kind of low cost andHighly active catalytic oxidation system, realizes with it and cleans, efficiently, the degree of depth removes organic sulfur in fuel oil.
Ionic liquid is as a kind of emerging " green solvent ", compared with traditional organic solvent, has many not comparableThe special performance of intending, mainly contains: fusing point is low, has wider liquid scope, can in wide range, select reaction temperature; GoodGood acidity, and in very large range acid adjustable; Almost there is no vapour pressure, non-volatile, nonflammable and blast, has avoided largeAmount volatile organic solvent pollution on the environment and the injury to operator are safe green replace solvents; Heat preferablyStability and chemical stability; Can reuse.
Magnetic ionic liquids is the earliest by discoveries such as Hayashi, by [Bmim] Cl and FeCl3Under nitrogen, react, get final productTo magnetic ionic liquids [Bmim] Cl/FeCl3, this ionic liquid can be responded to externally-applied magnetic field consumingly, has paramagnetism(Chem.Lett.,Vol.33,1590~1591,2004)。
Ionic liquid mainly contains two kinds of methods for the research of fuel desulfuration: directly abstraction desulfurization method and extraction coupling peroxideChange hydroxide doctor treatment; Li etc. by ion liquid abstraction and hydrogen peroxide oxidation in conjunction with and for the desulfurization of fuel oil, with 1-Butyl-3-methylimidazole iron chloride ([Bmim] Cl/FeCl3) be extractant and catalyst, the sulfur content in mould oil is by first1000ppm be reduced to 8ppm (GreenChem.Vol.11,810 ~ 815);
Ionic liquid-catalyzed oxidation sweetening system ionic liquid after reaction of report is thorough not with separating conventionally of oil productThe end,, adopt magnetic field to control separating of ionic liquid and oil product, and current application in this respect is not also reported.
Summary of the invention
