摘　　要：5-羟甲基糠醛(HMF)是生物质转化为化学品、燃料和聚酯材料的重要平台化合物之一。理性设计高效催化剂、优化催化反应过程、开发新型分离以及反应-分离单元耦合技术能够强化HMF生产综合效能,还可以简化工艺流程、降低碳排放和能耗。本文立足于酸催化己糖脱水合成HMF过程中反应和分离的关键科学问题,从催化剂活性位“接力式”设计、催化反应串联耦合、表面亲疏水性调控、反应溶剂匹配、固-液吸附材料、吸附机制和构-效关系、反应-分离过程强化等方面出发,系统综述酸催化己糖脱水合成HMF过程中的反应、分离和过程耦合相关研究进展,为生物质资源高效转化利用过程中催化和分离系统的综合设计提供参考与指导。5-hydroxymethylfurfural(HMF)is one of paramount platform chemicals for converting biomass into chemicals,fuels and polyester materials.The rational design of efficient catalysts,optimization of catalytic reaction processes,and development of the novel separation and reaction-separation coupling technologies can enhance the comprehensive efficiency in production of HMF,simplify the unit processes,and reduce carbon emissions and energy consumption.In this paper,the state-of-the-art towards catalytic reactions,separation technology and process coupling related during acid-catalyzed dehydration of hexoses to HMF were reviewed from the fundamentals in designing the bifunctional active sites for relay catalysis,integration of tandem reactions,regulation of surface hydrophilicity and hydrophobicity,selection of reaction medium,adsorbent materials,adsorption mechanism and structure-performance relationship,as well as process intensification.The knowledge and learning points gained from this review would be instructive for research communities working on catalysis and separation in biomass utilization.
