| Abstract: | The catalytic cracking unit plays an important role in the production of propylene-producing chemical raw materials.ZSM-5 can be used for catalytic cracking of propylene-producing active components because of its special pore structure,high activity,and shape-selective catalysis.In this paper,the research progress of improving the hydrothermal stability of ZSM-5 by post-modification and introducing mesoporous to improve the molecular accessibility are reviewed,mainly including F modification,P modification,transition metal doping and rare earth modification,and physicochemical dealumination-desilication,soft template method and hard template method to modify the channel of ZSM-5. |
