Cu/ZnO@H-β-P催化剂在合成气制备液化石油气反应中的性能研究
Research on the performance of Cu/ZnO@H-β-P catalyst in the reaction of LPG preparation from syngas
摘要
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.关键词
