ABSTRACT:
Zeolitic catalysts containing framework displaced aluminum, e.g., steamed or spent catalysts, are activated by contact with aqueous fluoride solution under mild conditions. The treatment can enhance catalytic activity, ion-exchange capacity and crystallinity by replacing aluminum in the zeolitic framework.
