Catalyst for hydrotreatment of hydrocarbons and method for production thereof.

摘要

A catalyst for the hydrotreatment of a hydrocarbon oil comprises a carrier of an inorganic oxide and an active component supprted on the carrier and formed of at least one member selected from the group consisting of water-soluble compounds of molybdenum, tungsten, and the metal of Group 8 in the Periodic Table of Elements and at least one mercapto (-SH) group-containing organic compound selected from the group consisting a mercaptocarboxylic acids represented by the general formula: HS-(CH2)n-COOR (wherein n stands for an integer in the range of 1 to 3 and R for a hydrogen atom, an alkali metal, an alkaline earth metal, ammonium, or a linear or branched naphthenic alkyl group having 1 to 10 carbon atoms), amino-substituted mercaptans represented by the general formula: H2N-R min -SH (wherein R min stands for a divalent hydrocarbon group), divalent mercaptans represented by the general formula: HS-R min -SH (wherein R min stands for a divalent hydrocarbon group), and thio acids represented by the general formula: R sec -COSH (wherein R sec stands for a monovalent hydrocarbon group).
