摘要
双功能催化剂可将CO/CO2加氢直接合成低碳烯烃、芳烃和汽油等,具有工艺流程短、能耗低的优势。双功能催化剂由金属氧化物和分子筛两部分组成,分子筛特定的腔体结构、酸性质及与金属氧化物的结合方式等均可显著影响其催化性能。该文综述了近年来分子筛在双功能催化剂中用于CO/CO2加氢反应的研究进展,简述了分子筛的类型、酸性质、形貌及颗粒尺寸、金属改性、分子筛与金属氧化物的结合方式等对双功能催化剂催化性能的影响规律,展望了双功能催化剂中分子筛的发展趋势。
Bifunctional catalysts can hydrogenate CO/CO2 directly to synthesize lower olefins,aromatics and gasoline,etc.,which has the advantages of short process flow and low energy consumption.Bifunctional catalysts are composed of metal oxides and zeolites.The specific cavity structures,acidic properties and the combination with metal oxides of zeolites can significantly affect the catalytic performances of catalysis.The research progress of zeolites used in CO/CO2 hydrogenation over bifunctional catalysts in recent years is reviewed.The effects of the types of zeolites,acidic properties,morphology and particle size,metal modification,combination of zeolite and metal oxide on the catalytic performance are summarized.The development trend of zeolites in bifunctional catalysts is prospected.
