Abstract:The effect of Na+ rarr H+ ion-exchange conditions on catalytic properties of the resulting H-ZSM-5 zeolites has been investigated. The concentration and mode of addition of the reactant to the exchange medium affect the degree of exchange achieved. During low-temperature conversion of olefins, the H-ZSM-5 zeolites have become rapidly deactivated. Thermal regeneration fully restores their original catalytic properties.
