METHOD OF DECREASING THE POTASSIUM CONTENT OF POTASSIUM-CONTAINING ZEOLITES

摘要

A method of decreasing the potassium content of a potassium zeolite containing calcium, such as erionite, which comprises calcining said zeolite and thereafter ion exchanging said zeolite with cations other than potassium. Potassium zeolites, such as zeolite-T, which do not contain calcium are ion exchanged with calcium cation prior to said calcining and ion exchanging. Catalytically active forms of the zeolite product are used in hydrocarbon conversion processes.
