摘要
Abstract
A variety of extraction technologies for dearomatization at present are mature and used widely in industry. However,high energy consumption and low economic benefits are the problem in dealing with naphtha feed with low aromatics content (mass fraction less than 15%). Extraction technologies for dearomatization are reviewed,focusing on extraction efficiency of conventional solvents and ionic liquids for aromatics in naphtha. Conventional solvents,such as sulfolane,N-methyl pyrrolidone and composite solvents,such as sulfolane (water)-triethylene glycol,sulfolane (water)-N-methyl pyrrolidone,sulfolane-2-propanol and RAH-1 display excellent results in deep dearomatization of straight-run naphtha. Those researches can be used as underlying data for the current processes. Imidazole ionic liquids,such as 1-butyl-3-methylimidazolium hexafluorophosphate,1-butyl-3- methylimidazolium bis(trifluoromethylsulfonyl)imide,1-butyl-3-methy-limidazolium tetrachloroforrate have more potential use in dearomatization process for naphtha of low aromatics by extraction. Therefore,development of new ionic liquids which can extract aromatics from complex feeds with low aromatic contents will be the new trend.关键词
