摘    要:石油化工生产中广泛使用的加氢脱硫催化剂往往是以v-A120。作为载体,Moo或WOs为主要活性组分,少量Nio或Coo为助剂的多组分负载型催化剂.由于它在生产中所起的重要作用,此类催化剂的研究一直受到科学工作者的关注.本文分别考察了几种不同组分的催化剂,研究了催化剂组分间的相互作用对活性组分的分散状态、还原性能以及加氢脱硫活性的影响,旨在为进一步改进催化剂的性能提供有益的信息.且实验部分Ni-MO体系催化剂样品是以银酸钦和硝酸镍及v-AI。0。为原料,采用浸渍方法制备.C。M。/AJ。0。和W-Ni/AJ。0。分别用硝酸钻…

关 键 词:加氢脱硫催化  X射线衍射  程序升温还原  X光电子能谱  协同效应

Abstract:The effects of the synergism among NiO, MoO3 and Al2O3 on the properties of the hydrodesulfurization (HDS) catalysts have been inveshgated by means of the techniques of XRD, TPR,XPS and chendsorption. The results indicate that the dispersion of MoO3 on the catalyst is improved owing to the presence of NiO. A complex on the suiface of the support, formed by the action of NiO with MoO3 can be easily reduced and sulphized. There is also synergism on catalysts Co-Mo/Al2O3 and Ni-W/Al2O3, but they differ from the one on Ni-Mo/Al2O3 in some aspects.
Keywords:Hydrodesulfurization (HDS) catalysts  XRD  TPR  XPS  Synergism effect
