| 摘 要： | 采用连续流动微反装置,考察了催化剂载体、载体焙烧温度、催化剂制备方法及催化剂中Ni/Mo配比对NiMo催化剂催化噻吩加氢脱硫反应性能的影响,并用BET,XRD和TPR对催化剂进行了表征。结果表明,催化剂载体影响催化剂的性能,对于无Ni助剂的催化剂,负载在TiO2载体上的Mo催化剂活性高于负载在ZrO2上的催化剂,而助剂Ni的添加改变了活性顺序,使负载在TiO2载体上的NiMo催化剂活性低于负载在ZrO2上的催化剂;催化剂制备方法影响催化剂的性能,以共浸法制备的催化剂表现出高的催化活性;Ni/Mo配比影响催化剂的性能,当Ni/Mo摩尔比为0 6时,催化剂具有最高活性。

| Abstract: | A series of Mo-based catalysts supported on ZrO_2 or TiO_2 were prepared.Thiophene hydrodesulfurisation (HDS) was taken as a model reaction for comparing catalysts activity.The catalysts were characterized by BET,XRD and TPR.Property of supports showed influence on catalyst activity.Catalytic activity of NiMo supported on ZrO_2 was higher than that supported on TiO_2.Moreover,catalyst activity increased with ZrO_2 calcinations temperature from 550 ℃ to 650 ℃.The catalysts were prepared by three methods,namely co-impregnation,wet mixing and multi-step impregnation.Catalyst by co-impregnation showed the highest activity.When Ni/Mo mole ratio was 0.6,the activity was best. |
