Lignocellulosic biomass provides an attractive source of renewable carbon that can be sustainably converted into chemicals and fuels. Hydrodeoxygenation (HDO) processes have recently received considerable attention to upgrade biomass-derived feedstocks into liquid transportation fuels. The selection and design of HDO catalysts plays an important role to determine the success of the process. This review has been aimed to emphasize recent developments on HDO catalysts in effective transformations of biomass-derived platform molecules into hydrocarbon fuels with reduced oxygen content and improved H/C ratios. Liquid hydrocarbon fuels can be obtained by combining oxygen removal processes (e.g. dehydration, hydrogenation, hydrogenolysis, decarbonylation etc.) as well as by increasing the molecular weight via C-C coupling reactions (e.g. aldol condensation, ketonization, oligomerization, hydroxyalkylation etc.). Fundamentals and mechanistic aspects of the use of HDO catalysts in deoxygenation reactions will also be discussed.
木质纤维素生物质提供了一种有吸引力的可再生碳源，可以将其可持续地转化为化学品和燃料。最近，氢解（HDO）工艺受到了广泛关注，可将生物质衍生的原料升级为液体运输燃料。HDO 催化剂的选择和设计对于确定该工艺的成功与否起着重要作用。本综述旨在强调 HDO 催化剂在将生物质衍生的平台分子有效转化为含氧量降低、H/C 比提高的烃类燃料方面的最新进展。通过组合脱除氧过程（例如脱水、加氢、氢解、脱羰等）以及通过 C-C 偶联反应（例如醇醛缩合、酮化、齐聚、羟烷基化等）增加分子量，可以获得液体烃类燃料。还将讨论 HDO 催化剂在脱氧反应中使用的基本原理和机理方面。
