High Si/Al ratio HZSM-5 supported Ga2O3: a highly stable catalyst for dehydrogenation of propane to propene in the presence of CO2

摘要：

High catalytic activity and stability of dehydrogenation of propane to propene in the presence of CO2 were achieved over Ga2O3 catalyst supported on HZSM-5 with high Si/Al ratio. The propene yield stabilized at about 22 ％ without observable deactivation in 100 h, which was thought to be caused by adjusting the acidity of the catalyst appropriately through dealumination of the zeolite. The reaction mechanism on the titled catalyst was discussed.
