Zeolites are well known catalysts for the conversion of methanol to hydrocarbons. By adjusting the synthesis procedure, the activity and deactivation of the ZSM-5 zeolite in the conversion of methanol to gasoline can be varied significantly. We found that internal framework defects are crucial for the deactivation behavior of the ZSM-5 catalysts. Adsorption of pyridine and 2,4,6-collidine shows that...
This study examined the reaction mechanism with respect to both catalyst deactivation and product formation in the conversion of methanol to hydrocarbons over zeolite H-ZSM-5. The reactivity of the organics residing in the zeolite voids during the reaction was assessed by transient 12 C/ 13 C methanol-switching experiments. In contrast to previously investigated catalysts (H-SAPO-34...
