Abstract: The research progress of heterogeneous W-based catalysts in olefin metathesis field, is reviewed, focusing on catalysts preparation, reaction mechanism and process conditions for heterogeneous WO3 catalysts, and also heterogeneous organic tungsten catalysts. Several key factors influencing catalyst performance are summarized, such as metal valence, configuration of oxide, acidity and dispersity. The research direction of heterogeneous W-based metathesis catalysts is proposed, to give guidance and advice for the development of high-performance tungsten catalysts.

Key words: olefin metathesis, heterogeneous catalyst, tungsten oxide, propylene

摘要： 综述了负载型钨基催化剂用于烯烃歧化领域的研究情况，着重介绍了负载氧化钨催化剂的制备、反应机理和工艺条件的研究，简要介绍了负载有机钨催化剂的研究进展。在此基础上，文章总结了影响负载氧化钨催化剂活性的几个重要因素，如中心金属（钨）的价态、金属中心的构型、催化剂的酸性以及负载金属的分散性等，并提出了负载型钨基歧化催化剂的研究趋势，希望能对以后开发高活性的氧化钨催化剂提供有益的指导和参考依据。
