Abstract:
The present invention pertains to a process for preparing a catalyst composition wherein at least one Group VIII non-noble metal component and at least two Group VIB metal components are combined and reacted in the presence of a protic liquid, after which the resulting composition is isolated and dried, the total of the Group VIII and Group VIB metal components, calculated as oxides, making up at least about 70 wt. % of the catalyst composition, calculated on dry weight. An organic oxygen-containing additive is added prior to, during, or subsequent to the combining and reacting of the metal components in such an amount that the molar ratio of the total amount of additive added to the total amount of Group VIII and Group VIB metal components is at least about 0.01. The invention also pertains to additive-containing catalysts obtained by this process, and to their use in hydroprocessing.
