Dimethyl Ether Conversion to Gasoline Hydrocarbons over Nanosized Zeolite Catalysts: Effect of Modifier Nature

详细

The effect of modifier nature on the catalytic properties of nanosized zeolite catalysts used for the synthesis of liquid hydrocarbons from dimethyl ether is studied. It is shown that selectivity of the catalysts for liquid hydrocarbons depends on both the modifier nature and the initial feedstock composition. The best activity and selectivity for liquid hydrocarbons are exhibited by the samples modified with zinc and magnesium. The content of aromatic hydrocarbons in the products decreases appreciably when the catalysts are additionally modified with noble metals and the reaction is carried out in the medium of hydrogen.
