Since the catalytic activities of cation exchanged X and Y zeolites were discovered in 1960's synthetic zeolites are widely used as the industrial catalysts and the advances of zeolite catalysts led many technical innovations in oil refining and petrochemical processes. Recently, there has been strong interest in catalytic application of newly synthesized large pore zeolites or meso porous materials those are such as MCM-41, CIT-1 or MCM-22. In this paper, the progresses of zeolite catalysts commercially used are reviewed and recent topics of zeolite catalysts are also discussed.
