Abstract: The article reveals the function of Zr, B and P as a third component added on the support of silica-alumina, and the ways of introduction of the third component effecting on the properties of the support. The results shows that introducing Zr on the support in chelating ways is the best, because it can make the active metals dispersed well on the surface of the catalyst, and can also produce superior mutual reactions between the support and active metal, which brings about better activities.

Key words: sulfided catalyst; support; mutual reaction; hydrotreating
