Abstract
A series of nickel or cobalt promoted molybdenum catalysts and one nickel-tungsten catalyst have been studied by oxygen chemisorption on reduced oxidic samples, by activities of oxidic and sulphided samples for 1-hexene hydrogenation and by activities of sulphided samples for benzothiophen and pyridine hydrogenolyses. A good correlation was obtained between oxygen chemisorption and hydrogenation activity on oxidic, partially reduced, forms of the catalysts, and a limited correlation for activities of sulphided forms. Parallel activities for hydrogenation and hydrogenolyses were observed.
