摘　　要：以负载于γ-Al2O3的Mo及Ni-Mo金属氧化物为前躯体,采用程序升温方法,分别制备了负载型Mo及Ni-Mo氮化物和碳化物催化剂。采用元素分析、X射线衍射(XRD)、程序升温还原(H2-TPR)技术对所制备的催化剂进行了表征,并考察了它们对苯甲酸乙酯的加氢脱氧(HDO)反应的催化性能。结果表明,负载型Mo及Ni-Mo氮化物及碳化物对苯甲酸乙酯HDO反应都具有很高的催化活性,且碳化物比氮化物更为稳定。在HDO反应过程中,积炭可能是造成催化剂失活的重要原因。From Mo and Ni-Mo oxide supported on γ-Al2O3,Mo and Ni-Mo nitride and carbide catalysts were synthesized by means of temperature-programmed reaction.The characterization of these samples was performed by elemental analysis,X-ray diffraction（XRD）,and temperature-programmed reduction（H2-TPR）.The hydrodeoxygenation（HDO）performance of the nitride and the carbide catalysts was also investigated by using ethyl benzoate as a model compound.The results indicated that both the nitride and carbide exhibited high activities for HDO of ethyl benzoate,but carbide was superior to nitride on stability.The coke deposition may be the main reason of the catalyst deactivation during HDO.
