Abstract
A method of preparing a catalyst for hydrogenation of a hydrocarbon oil, wherein an aqueous solution containing a metal of Group VI of the Periodic Table and a metal of Group VIII of the same, along with a hydroxycarboxylic acid and optionally phosphoric acid is added to a carrier substance consisting essentially of at least one of an inorganic oxide and an inorganic hydrate, and the resulting blend is kneaded, shaped and thereafter dried at a temperature not higher than 200.degree. C. The catalyst has a high catalyst activity and is used for hydrogenation of a hydrocarbon oil, especially satisfying the requirement of reducing the sulfur content in a light oil.
Claims16
A method of preparing a catalyst for the hydrogenation of a hydrocarbon oil without calcination which consists of the steps of (a) providing a carrier substance consisting essentially of at least one of an inorganic oxide and an inorganic oxide hydrate, (b) contacting said carrier substance with an aqueous solution containing ions of a metal from Group VI of the Periodic Table, ions of a metal from Group VIII of the Periodic Table and hydrocarboxylic acid to form a blend, (c) kneading and shaping said blend, and (d) heating said blend to a temperature not higher than 200.degree. C.
