随着石油资源储量的减少，生物油作为石油替代能源备受人们的关注。生物油中含有较多的含氧化合物，氧质量分数一般超过30％。因此其热值较低，热稳定性较差，须对其进行加氢精制以脱除其中的氧。加氢脱氧（HDO ）是对生物油进行提质的有效途径，反应过程中常用的催化剂为传统的硫化态加氢催化剂或还原态金属催化剂。简单概述了含氧化合物加氢脱氧催化剂的类型、催化剂失活的原因及提高催化剂稳定性的方法，并就未来研究方向和提高催化剂性能的改进措施提出了建议。

As the oil reserves are decreasing , bio‐oil as an alternative fuel source has attracted much attention .Bio‐oil contains a lot of oxygenic compounds and the oxygen content is generally more than 30% , leading to its low heating value and thermal instability , so it must be hydrotreated to remove the oxygen .Hydrodeoxygenation (HDO) is an effective way to upgrading bio‐oil .Catalysts for HDO are the traditional hydrodesulphurization (HDS ) catalysts , such as Co‐MoS2/Al2 O3 or metal catalysts .The type of catalysts used for bio‐oil HDO , the reason of catalyst deactivation and the method to improve the stability of catalyst were reviewed , in addition , the future research direction and the effective way for improving the catalyst activity were proposed .
