摘要
合成气催化转化是生物质或煤炭资源化清洁利用的重要路径,由此可获得烯烃和芳烃等多种高附加值碳氢化合物。分子筛由于具有独特的亚纳米孔道、可控活性位及分子择形性等优点,常被作为载体或直接作为活性组分用于催化合成气转化中C−C的形成和断裂等关键步骤。本综述总结了以分子筛负载金属、氧化物-分子筛(OX-ZEO)双功能以及核壳结构催化剂等直接催化转化合成气制备碳氢化合物的研究进展。重点介绍分子筛结构和酸性对反应路径和机理以及产物分布的影响,并展望分子筛催化合成气转化的未来发展方向。
The catalytic conversion of syngas to value-added hydrocarbons is an important strategy for the clean utilization of biomass and coal resources.Zeolites as supports and/or catalytic components are commonly used for C–C formation/cleavage in the syngas conversion,owing to their unique microporous structure,accurately tunable active sites,and molecular shape-selectivity.Herein,we have surveyed the research progress of direct conversion of syngas to hydrocarbons by using metal-loaded zeolites,bifunctional oxide-zeolite(OX-ZEO),and core-shell structured catalysts,focusing mainly on the influence of zeolite structure and acidity on the reaction mechanism as well as the product distribution for syngas conversion.In addition,an outlook is given on the perspective of zeolite synthesis and catalysis in the direct conversion of syngas.
