| 摘 要： | 采用等体积浸渍法制备加氢催化剂NiMo/γ-Al2O3,在悬浮床上考察不同的制备条件下NiMo/γ-Al2O3对萘加氢生成四氢萘的影响。结果表明,催化剂的制备条件对加氢活性有显著的影响,NiMo/γ-Al2O3催化剂的最佳制备条件为共浸渍法负载金属组分Ni和Mo,在500 ℃的温度下焙烧4 h。此条件下制备的催化剂上四氢萘的选择性高达95.2%。

| Abstract: | NiMo/γ-Al2O3 catalyst was prepared by equal volume impregnation.The effects on the hydrogenation of naphthalene to tetralin of NiMo/γ-Al2 O3prepared by different conditions were investigated on a slurry-phase hydrocracking reactor.The results show that the catalysts prepared under different conditions have a significant influence on the hydrogenation activity.The optimal preparation conditions of NiMo/γ-Al2O3 catalyst are as follows:the metal components Ni and Mo are supported by the co-impregnation method,and the calcination is performed at 500 ℃ for 4 h,under this condition,the selectivity of tetralin is up to 95.2%. |
