HETEROGENEOUS CATALYSTS FOR PROPYLENE OLIGOMERIZATION

Advances in heterogeneous catalysts for propylene oligomerization in the last ten years was reviewed.The kinds,structure and properties of carriers,the kinds,valent state and migration mech- anism of metal cations were discussed.Active sites of the catalysts,formation of intermediates in the reaction and catalysis mechanism were also discussed.The problem with the heterogeneous catalysts for propylene oligomerization was the loss of the active sites in the reaction.Research and develop- ment of new carriers and additives stabilizing active sites were emphasized,which was the focus of the research for heterogeneous catalysts.
