Abstract: The research of C₄-olefin to produce propylene was the emphasis of aliphatic olefin metathesis technology，but attentions were also paid to longer-chain aliphatic olefins metathesis reaction. The progress of the metathesis reaction of longer-chain aliphatic olefins over rhenium based catalysis，molybdenum based catalysis and tungsten based catalysis were introduced. The study of longer-chain olefin metathesis over tungsten based catalyst，including the optimal operating condition of 1-hexene self-metathesis，1-heptene self-metathesis and 1-octene self-metathesis. The effect of pretreatment on metathesis performance of tungsten based catalyst is primarily introduced. Moreover，the studies of deactivation of metathesis catalyst by oxygenate poisoning and deactivation of tungsten based catalyst by coke formation are also introduced.

Key words: metathesis, rhenium based catalyst, molybdenum based catalyst, tungsten based catalyst

摘要： 目前，虽然直链烯烃歧化研究的重点仍是碳四烯烃歧化制丙烯技术，但是长碳链烯烃歧化研究已开始引起人们的重视。本文介绍了铼基催化剂、钼基催化剂和钨基催化剂催化长碳链烯烃歧化反应的研究进展。重点介绍了钨基催化剂上长碳链歧化研究状况，分别介绍了钨基催化剂上1-己烯自歧化、1-庚烯自歧化、1-辛烯自歧化的最优工艺条件研究以及预处理条件对钨基催化剂歧化性能的影响。同时分别介绍了含氧化合物对歧化催化剂中毒失活的研究以及钨基催化剂上结焦失活的研究状况。
