ABSTRACT:
Catalysts for hydrotreating hydrocarbons are composed of a carrier substance consisting essentially of an oxide of aluminum and/or an oxide hydrate of aluminum, at least one compound selected from water-soluble compounds of metals of Group VI and Group VIII of the Periodic Table and at least one organic compound selected from mercapto-carboxylic acids of formula HS--(CH.sub.2).sub.n --COOR (where n is 1 to 3; R is H, alkali metal, alkaline earth metal or ammonium group or alkyl group with 1-10 carbons), thio-acids of formula R'--COSH (where R' is monovalent hydrocarbon with 1-15 carbons), amino-substituted mercaptans of formula H.sub.2 N--R"--SH (R" is divalent hydrocarbon with 1-15 carbons), dimercaptans of formula HS--R"--SH (R" is same as above) and mercapto-alcohols of formula (R.sup.a S--R"'--(OH).sub.n (where R"' is hydrocarbon with 1-15 carbons; R.sup.a is H or alkyl group with 1-2 carbons; and n is 1-2), and optionally phosphoric acid. The catalysts require neither presulfurization nor heat-treatment and can be directly applied to hydrotreating hydrocarbons.
