Zeolite Catalysts for the Synthesis of Lower Olefins from Dimethyl Ether (a Review)
This review presents the recent achievements in the field of development of zeolite catalysts for the production of lower olefins from dimethyl ether. The characteristic features of the influence of the topology and acidity on the conversion of dimethyl ether are discussed. The data on various methods for increasing the selectivity of zeolite catalysts in the conversion of dimethyl ether to lower olefins are summarized. The possible methods of changing the acidic properties of zeolites, namely, modification by cations of various elements, hydrothermal treatment of zeolite catalysts, and variation of the SiO2/Al2O3 molar ratio are considered.
