Mechanism of Catalyst-life Lost and Activity Regeneration of ZSM-5 Catalysts in DTO Reaction |
초록 |
Regeneration of H-ZSM-5 catalyst was tested on DME conversion to olefin. The catalyst life was stabilized by the regeneration for a number of reactions. Since the decreases in both acid amount and surface area were observed, the regeneration must cause the change of structure, that is, dealumination. To confirm this assumption, dealuminated H-ZSM-5 was synthesized by steaming treatment so that the catalyst life was prolonged. The dealumination from zeolite framework was made progress via the formation "unstable Al species" and the their change to extra-framework. |
