The process of regeneration of Pentasil type of zeolites and its influence on the nature of the coke deposits in the reaction of methanol conversion into hydrocarbons is studied. It is shown that in the course of complete reaction-regeneration cycles hydrothermal processing of the catalysts occurs with dealuminization of the zeolite and slowing of coke formation. Condensation of the structures of the coke deposits increases with increase of dealuminization. Prolonged hydrothermal treatment causes irreversible deactivation of zeolite catalysts.
