Catalysts for hydrotreating hydrocarbons and method of activating the same.

摘要

New supported catalysts for hydrotreating hydrocarbons comprise (a) at least one member selected from the group consisting of oxides of metals in the Periodic Table's Groups VI and VIII, 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 new catalysts can be easily activated by treatment in the presence of hydrogen gas at a temperature in the range from room temperature to 400 DEG C, showing higher activity than those activated by conventional methods.
