Hydrodesulfurization (HDS) of dibenzothiophene and hydrodenitrogenation (HDN) of aniline over Co-Mo on TiO{sub 2}-ZrO{sub 2}-V{sub 2}O{sub 5} catalysts over Co-Mo on {gamma}-Al{sub 2}O{sub 3} catalysts were investigated and compared in a continuous-flow microreactor at 240-350{degree}C and 3.55 MPa. HDS and HDN activities on Ti/Zr/V-supported catalysts depended on the amounts and the order of impregnation of molybdenum and cobalt. It was found that Ti/Zr/V-supported catalysts has higher HDS and HDN activities than alumina-supported catalysts. The optimal amounts of CoO and MoO{sub 3} on TiO{sub 2}-ZrO{sub 2}-V{sub 2}O{sub 5} were much less than on alumina. Moreover, the mutual inhibition of HDS and HDN over Ti/Zr/V-supported catalysts was less pronounced than that over alumina-supported catalysts. The Ti/Zr/V-supported catalyst was also more active than the commercial catalyst, HR-306, in hydrodesulfurization of petroleum feedstocks.
