摘　　要：烯烃交叉复分解反应作为石油化工领域一种重要过程,为各种单烯烃间的互相转化提供了一条有效的途径。特别是在利用正丁烯生产丙烯和其它重要单烯烃方面,复分解反应受到越来越多的重视。本文对烯烃交叉复分解反应(CM)的进展进行了综述,讨论了CM各种工艺的技术特点及反应机理,重点介绍了WO3/SiO2、Re2O7/Al2O3、MoO3/Al2O33类催化剂的最新改进及相应的理论分析,试图理清催化剂今后发展的思路,为进一步改进催化剂的性能提供相关的依据。Olefin metathesis opens up new industrial processes for the production of important olefins in the field of petrochemicals. In particular, the production of propylene and other important olefins via olefin metathesis reaction from n-hutches feedstock has received considerable attention. The most recent progress of olefin eross-metathesis reaction process, reactive mechanism, catalytic theory and catalysts for metathesis is reviewed in this paper and we try to explain the improved aspect of catalyst performance and provide reference for the study of metathesis catalyst afterwards.
