摘　　要：以合成气作为平台化合物一步法制备低碳烯烃和液体燃料是有效利用碳资源的重要路径,具备流程短、能耗低的特点,有着良好的工业应用前景。合成气一步法直接转化制备低碳烯烃和液体燃料包括两条工艺路线:费托合成路线和双功能催化路线。本综述简述了两种路线的反应机理,重点阐述了费托合成路线中采用添加助剂和惰性载体对铁基和钴基催化剂的优化设计,费托金属粒径、反应条件、催化剂界面结构对催化剂性能和反应过程的影响。详细解析了双功能催化路线中,一氧化碳活化组分和酸性分子筛的选择、金属氧化物粒径与元素比例、分子筛酸度与孔径大小以及一氧化碳活化组分和酸性分子筛的耦合方式对于催化剂性能的影响。总结了两条路线所具备的优势和面临的挑战,并对未来高效催化剂的发展方向进行了展望。One-step synthesis of light olefin and liquid fuel using syngas as platform compound is an important way to effectively utilize carbon resources.It has the characteristics of short process,low energy consumption,and is of good industrial application prospects.The one-step direct conversion of syngas to prepare light olefins and liquid fuels consists of two process routes:the Fischer-Tropsch(F-T)route and the bifunctional catalytic route.In this paper,the reaction mechanisms of both routes are briefly described.The optimal design of Fe-based and Co-based catalysts by inert supports,the effect of F-T metal particle size,reaction conditions,and catalyst structure on the catalytic performance and reaction process have been elaborated.In the bifunctional catalytic route,the influences of the CO activation components,zeolite type,the proportion and particle size of the metal oxide elements,the acidity and pore size of zeolites and the methods for coupling the CO activation components and zeolite on the performance of the catalysts were analyzed in detail.The advantages and challenges of the two routes are summarized.The development trends of efficient catalysts in the future have also been prospected.
