Abstract: The research progress of olefin cracking and the improvement of hydrothermal st ability of catalysts have been reviewed in this paper. The advances in zeolite m odification as well as the influence on catalytic performance of cracking olefin s were summarized. It would be valuable for the development of effective and app licable catalysts for the cracking of less valuable hydrocarbon feedstock to pro pene.
