Olefin disproportionation is a kind of reaction that generates new olefin molecules by C-C bond rearrangement. It can regulate the formation of target products according to market demand and is an important way to efficiently convert and utilize hydrocarbon resources. Compared with the homogeneous catalyst, the olefin disproportionation heterogeneous catalytic system has the advantages of easy preparation, simple separation and recyclable regeneration, and has good application prospect in large-scale chemical production. From the aspects of preparation methods, application types and reaction mechanism, the research status and the latest progress of heterogeneous catalytic reaction of olefin on disproportionation of olefins are mainly described.
