Supported catalysts for hydrotreating hydrocarbons comprise (a) at least one member selected from the group consisting of oxides of metals in Groups IV and VIII of the Periodic Table, and (b) at least one organic compound having a mercapto radical or radicals (－SH) selected from the group consisting of mercapto-carboxylic acids, including alkali metal, alkaline earth metal and ammonium salts thereof and esters thereof, bivalent mercaptans, amino-substituted mercaptans, and thiocarboxylic acids. These catalysts can be easily activated by treatment in the presence of hydrogen gas at a temperature in the range from room temperature to 400°C. show higher activity than catalysts activated by conventional methods.
