Zeolites are increasingly finding use in the production of petrochemicals, often replacing environmentally unfriendly catalysts.

Zeolite catalysts typically yield fewer impurities, have higher capacity, give greater unit efficiency, and afford higher selectivity. Unlike the more hazardous acid catalysts that have been used in the past, e.g., solid phosphoric acid, hydrofluoric acid, etc., zeolites are non-hazardous, regenerable, and non-corrosive.
