HYDROGENATION CATALYST AND ITS PREPARATION

PURPOSE:To exhibit catalytic activation of a nickel and obtain a highly active hydrogenation catalyst by controlling the sulfurization condition of a nickel or controlling the coordination condition of a nickel with a molybdenum or a tungsten. CONSTITUTION:A catalyst contains 20-95wt.% of alumina co...

Zusammenfassung:	PURPOSE:To exhibit catalytic activation of a nickel and obtain a highly active hydrogenation catalyst by controlling the sulfurization condition of a nickel or controlling the coordination condition of a nickel with a molybdenum or a tungsten. CONSTITUTION:A catalyst contains 20-95wt.% of alumina contains delta-alumina and theta-alumina in 10wt.% and more and cobalt aluminate in a concentration to give I782/I777>=1.0 by photoelectro spectroscopy and containing cobalt in 1-20wt.% calculated as CoO. Then the catalyst contains a nickel oxide, a molybdenum oxide, and a tungsten oxide in 1wt.% and more. By this composition, active metals of nickel, molybdenum, and tungsten especially nickel are suppressed from being formed into aluminates and thus a hydrogenation catalyst, especially a catalyst highly active for hydrogenation of a hydrocarbon oil can be obtained.
