Study of the Catalytic Performance and Deactivation of ZSM-22 Zeolite

ZSM-22 zeolite was prepared byhydrothermal synthesis and its catalytic performance and deactivationbehavior in methanol to olefin (MTO) were explored. The results suggest thatlow temperature is unfavorable to the activation of methanol, whereas themethanol conversion can be significantly increased with the increase ofreaction temperature. Meanwhile, the elevation of reaction temperature canenhance the contribution of alkene cycle, leading to the improvement of theselectivity of propene and butene...
