Abstract: The Cu/ZnO catalyst was prepared by the coprecipitation method, and the H-β zeolite was prepared by the hydrothermal synthesis method, and the bifunctional catalyst Cu/ZnO@H-β-P with core shell structure was prepared by the physical envelope method. The catalysts were used in the reactions of LPG preparation from syngas. The catalysts were characterized by the means of XRD, BET, NH₃-TPD and SEM-EDS. The activity of the catalysts was evaluated by a continuous flow fixed bed reactor. The results show that the Cu/ZnO@H-β-P catalyst was the mesoporous material with core shell structure, and the acid intensity of H-β zeolite was changed, and the cascade reactions from methanol to dimethyl ether to LPG were promoted by core-shell synergy in the Cu/ZnO@H-β-P catalyst. The CO conversion and LPG selectivity were higher on the Cu/ZnO@H-β-P catalyst with core shell structure than those on the Mix-Cu/ZnO-H-β catalyst. The catalyst activity was affected by the reaction conditions of space velocity and reaction temperature. The best space velocity and reaction temperature were 2 400 h^-1 and 350℃. The CO conversion and LPG selectivity achieved respectively 57.22% and 60.52% in the reaction of LPG preparation from syngas at the best reaction conditions using the Cu/ZnO@H-β-P catalyst.
