Study of Magnesium-Containing Zeolite Catalysts for the Synthesis of Lower Olefins from Dimethyl Ether

The catalytic properties of magnesium-containing zeolite catalysts in the synthesis of olefins from dimethyl ether (DME) were studied. The optimal concentrations of magnesium in the zeolite catalyst were found, and a procedure for its introduction was developed. The effect of the operation conditions of DME conversion into lower olefins on the catalyst activity and selectivity was studied. The stability of the catalytic properties of the synthesized catalyst after oxidative regeneration was examined.
