Abstract:

The effects of the synergism among NiO, MoO3 and Al2O3 on the properties of the hydrodesulfurization (HDS) catalysts have been investigated by means of the techniques of XRD, TPR,XPS and chemisorption. The results indicate that the dispersion of MoO3 on the catalyst is improved owing to the presence of NiO. A complex on the surface 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.

Key words: Hydrodesulfurization(HDS) catalysts, XRD, TPR, XPS, Synergism effect
