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
