摘　　要：综述了含氧化合物在金属碳化物/氮化物、金属磷化物催化剂上的加氢脱氧(HDO)催化性能,简述了这几种类型催化剂的HDO机理。其中,金属碳化物/氮化物、金属磷化物活性虽高,但金属碳化物/氮化物与氧物种的强相互作用,容易导致催化剂失活,而金属磷化物催化剂极易与HDO反应中产生的水反应,造成催化剂失活。另外,还介绍了载体在HDO反应过程中的作用,发现载体的酸性对催化剂的HDO性能的影响明显。最后,对今后加氢脱氧技术发展方向进行了展望。The hydrodeoxygenation（HDO） catalytic performance and the HDO catalytic mechanism of oxygen-containing compound were reviewed in details, using metal carbide catalysts, metal nitride catalysts and metal phosphide catalysts. Metal nitride/carbide catalyst and transition metal phosphide catalyst have shown to be effective for bio-oil HDO, but the strong interaction between oxygen and metal nitride/carbide easily leads to the catalyst deactivation. The reaction between the metal phosphide catalyst and water, which is produced in the HDO process, will lead to the catalyst deactivation. In addition, the effects of catalyst support on the catalytic activity are also discussed. The influence of acidity of the support on the HDO performance of the catalyst is obvious. Furthermore, future technologic explorations for the efficient HDO of oxygen-containing compounds are proposed.
