Mo, W, Co, and Ni sulfided catalysts exhibited relatively low activity in both HDS and o-HYD. For these sulfides, the TiO2 and ZrO2 support effect relative to c-Al2O3 varied by the factor 0.4–9.3. In contrast, the supported sulfides of Rh, Re, Pd, Pt, and Ir were highly active in HDS with low TiO2 and ZrO2 support effect relative to c-Al2O3 (Rh/ZrO2 being an exception). Rh, Re, and Pd sulfided species exhibited relatively low activities in o-HYD reaction while Ir and Pt species exhibited high activities in o-HYD. The reference industrial bimetallic CoMo and NiMo Al2O3 supported catalysts exhibited desirable high HDS but low o-HYD activities.
