摘　　要：异丁烯叠合-加氢可获得高辛烷值的异辛烷,是生产烷基化油的新途径,被称为间接烷基化技术。本 文介绍了这一技术的催化剂、工艺以及工业化过程的新进展。国内外的发展状况表明,间接烷基化技 术已趋成熟,将在清洁汽油的生产中发挥重要作用。The indirect alkylation process, a novel route for the production of alkylate, is introduced in this paper. This route is carried out in two steps; selective dimerization of isobutene (from C4 steams) to form di-isobutene, and hydrogenation to form saturated product isooctane. Stress is given to the development of new catalysts, processes and commercial technologies. The worldwide development trends in this challenging area show that indirect alkylation technology is moving towards maturity and will play an important role in the production of clean fuel.
