Advance of alkylation process and concentrated sulfuric acid alkylation reactor
摘要
Abstract
At present, the research of alkylation is mainly focused on the development of new catalysts and the strengthening of acid-hydrocarbon mixing process. The development of novel liquid acid alkylation reactors is one of the breakthrough points. In this paper, the status of alkylation technology at home and abroad were reviewed. The reaction process of solid acid,sulfuric acid,hydrofluoric acid and ionic liquid as catalyst were introduced. The mechanism of C4 alkylation was also reviewed. Based on the fact that the H-transfer of isobutane is the control step of the reaction, it was reported in this paper that the key of the development of alkylation is to strengthen the mass transfer of isobutane to acid phase, which is of great significance to the design of novel reactors. The reactors for concentrated sulfuric acid alkylation,which are divided into stirred mixing type, static mixing type, injection mixing type and shear mixing type according to the different ways of mixing,were emphatically introduced. This paper discusses several typical sulfuric acid alkylation reactors, including reactants mixing, products separation, and heat transfer. The advantages and disadvantages of various reactors are summarized,which is convenient for refiners to choose the reasonable alkylation reactor and process route.关键词
