HYDROGENATION CATALYST AND ITS PRODUCTION

Title:

HYDROGENATION CATALYST AND ITS PRODUCTION

Document Type and Number:

Japanese Patent JPH04210240

Kind Code:

A

Abstract:

PURPOSE: To obtain a highly active hydrogenation catalyst by depositing a catalytic metal on a carrier and dry-sulfurating the metal without calcining it.

CONSTITUTION: Catalytic metals such as molybdenum, cobalt and nickel are singly or plurally deposited on a carrier of γ-alumina, etc. The metals are heated, dehydrated and sulfurated in a reducing atmosphere without being calcined and without the metal salts depositing on the catalyst surface being converted to their oxides to obtain different surface structures. Heavy hydrocarbons are hydrogenated and efficiently reformed or cracked by the catalyst thus obtained.
