It is difficult to handle, and hydrofluoric acid highly volatile itself and has severe toxicity, once leakage can cause considerable damage to environment.In addition, above-mentioned
There is the phenomenon that severe corrosion equipment in two kinds of techniques, therefore develop low novel of environmental-friendly, corrosion-free to equipment, sour consumption and urge
Agent is most important.
Currently, the more new catalyst that can be used for synthesis of alkyl carburetion of research mainly include solid acid catalyst and from
Sub- liquid catalyst two major classes.Wherein solid acid catalyst mainly includes molecular sieve, solid super-strong acid (such as heteropoly acid), but this
Often there is the problems such as acid strength is unevenly distributed, acid activity bit number of points are less in a little catalyst, cause its reactivity worth bad, and
This kind of catalyst is easy to carbon distribution inactivation in the reaction due to the limitation of cellular structure.
The reaction raw materials that traditional synthesis of alkyl carburetion uses is iso-butanes and butylene, due to iso-butane during the reaction
It is often excessive, and excessive iso-butane is needed through deep cooling (lower than subzero 25 DEG C) Lai Huishou, therefore energy consumption is big, and China
C4Insufficient situation is also presented in the yield of hydro carbons, therefore process costs are consequently increased, and new alkylate oil is closed
It is of great significance at the research of technique.In the oil refining industry in China, can all there be a large amount of C every year3And C5Hydro carbons produces
Raw, the separation of these substances generally requires to consume a large amount of fund, if these substances rationally used, to produce alkane
Base carburetion can realize the recycling of tail gas while saving refinery tail gas recycle cost.At present with C3And C5Hydro carbons closes
It is had not been reported at alkylate oil, double acidic ionic liquid catalysts provided by the invention with a variety of acidic sites can be effective
It is catalyzed isopentane-propylene alkylated reaction, and isopentane is liquid at normal temperature, does not need to recycle by deep cooling, Ke Yijie
About mass energy opens new approach for the synthesis of alkylate oil, has important economic value.
