International ClassesB01J 23/88 (20060101)B01J 23/76 (20060101) AbstractA non-aqueous method of preparing an improved silica supported hydrotreating catalyst by reacting a mixture of Mo(Cl)5 and Ni(H2 O6)Cl2 and/or Co(H2 O)6 Cl2 in the presence of acetonitrile and impregnating a dried silica support with said mixture. The impregnated support is dried and sulfided before it is used in a hydrotreating process. |
