A combined catalytic system composed of catalysts with different functions was prepared. The catalyst for the synthesis of lower olefins based on is H-ZSM-5 zeolite modified with Mg, was mixed with the catalyst for alkylation of isobutane by olefins based on H-Y zeolite modified with La and Pd. In the presence of the combined system, liquid branched hydrocarbons were synthesized from dimethyl ether in a hydrogen medium at 340 °C and a pressure of 10 MPa. The effect of the composition of the combined catalyst on its selectivity to liquid hydrocarbons and, specifically, triptane was shown.
