In the research on upgrading of coal derived oils, the studies on the heteroarom-removal and the nuclear hydrogenation of aromatics are extremely important. We have previously reported the results of the Ru supported on nonacidic-metal oxide catalysts for the nuclear hydrogenation of polycyclic aromatics. In this paper, two types of catalysts such as Ru/Mn_2O_3-NiO and P_2O_5-Mn_2O_3-NiO were tested for the heteroatom-removal of dibenzothiophene and carbazole. The results showed that these catalysts were more active for the hydrodenitrogenation of carbazole than a commercial Ni-Mo catalyst, but less active for the hydrodesulfurisation than the commercial one. Furthermore, it was found that the phosphate on the catalyst behaved the resistance to the sintering of the support.
