费托合成直接制航空煤油中双功能催化剂的研究进展OA北大核心
Research progress on bifunctional catalysts for direct synthesis of jet fuel from Fischer-Tropsch synthesis
费托合成可将生物质来源的合成气直接转化为航空煤油(简称"航煤"),是最具应用前景的生物航煤生产技术之一.受Anderson-Schulz-Flory(ASF)分布规律的限制,费托合成直接制航煤的产物选择性有限,如何提高航煤选择性仍是当前该领域面临的重要挑战.利用双功能催化剂可将费托合成活性中心与分子筛酸中心耦合,可实现CO加氢与裂解、异构化等二次反应的接力,进而达到有效调控特定馏分选择性的目的.介绍了双功能催化剂的作用机理,对比了现有报道中费托合成的反应性能,阐述了尺寸效应、孔结构调控、酸性质调控和助剂效应在不同催化体系中的调控策略及构效关系,并对双功能催化剂在费托合成直接制航煤中的应用进行了展望.
Fischer-Tropsch synthesis(FTS)can directly convert syngas derived from biomass into jet fuel,making it one of the most promising technologies for producing bio-based jet fuel.However,the selectivity of jet fuel in direct FTS is limited by the Anderson-Schulz-Flory(ASF)distribution law,posing a significant challenge in improving selectivity of jet fuel.Bifunctional catalysts,which couple FTS active centers with zeolite acid centers,enable the relay of CO hydrogenation with secondary reactions such as hydrocracking and isomerization,effectively controlling the selectivity for specific fractions.The mechanisms of bifunctional catalysts were introduced,and the reaction performances reported in existing studies were compared.The synthetic strategy and structure-performance relationship in different catalytic systems were emphasized,including the size effect,pore structure and acidity control of zeolites,as well as promoter effect.An outlook on the application of bifunctional catalysts for direct synthesis of jet fuel from FTS was provided.
