Dimethyl Ether Conversion to Liquid Hydrocarbons: Effect of SiO2/Al2O3 Molar Ratio and Zinc Introduction Method on the Properties of a Nanosized Zeolite Catalyst

The effect of the SiO2/Al2O3 molar ratio in Zn/ZSM-5 nanosized zeolites, the nature of original zeolite ZSM-5, and the method of introducing zinc cations into the zeolite structure on its physicochemical and catalytic properties in dimethyl ether conversion to a mixture of synthetic liquid hydrocarbons is studied. It is shown that an increase in the SiO2/Al2O3 molar ratio leads to rise in selectivity for liquid hydrocarbons and in the content of isoparaffins and aromatic hydrocarbons in them. The method of zinc incorporation into the composition of nanosized ZSM-5 slightly affects selectivity for liquid hydrocarbons and their group hydrocarbon composition.
