    Direct synthesis of liquid hydrocarbons from СО2 and Н2 on a combined bifunctional catalyst consisting of ZnAlOx or ZnCrOx (oxide catalysts for the synthesis of hydrocarbons from СО and Н2) and HZSM-5 zeolites with different SiO2/Al2O3 molar ratios was studied. The physicochemical characteristics of the zeolites, namely, acidity evaluated by temperature-programmed ammonia desorption, porosity, and specific surface area, were examined. The catalyst performance was studied on a micro-pilot installation in the flow recirculation mode at 340°С and a pressure of 10 MPa. The ZnAlOx/ZnZSM-5(40) catalyst exhibits the highest selectivity to С5+ hydrocarbons, which is associated with the presence of strong Brønsted acid sites on its surface.
