The subjects discussed in this article are concerned with the nature and the formation of active sites of zeolites and their catalytic actions in organic reactions. Taking recent studies into account, it is reasonable that the active species of hydrogen zeolites is proton formed by deamination of ammonium ion exchanged with sodium cation, and that of zeolite catalysts exchanged by multivalent cations is also proton dissociated from adsorbed water in the electrostatic field of the zeolite.<BR>Zeolites are active in cracking, isomerization alkylation and the other reactions of hydrocarbons. Since the surface area is large, they are also used as effective supports in hydrogenation, oxidation and dehydrogenation of hydrocarbons.<BR>Subsequent discussions and elucidation are done on the catclitic actions of zeolites in these reactions.
