Abstract
The invention pertains to a process for preparing a catalyst composition comprising bulk catalyst particles comprising at least one Group VIII non-noble metal and at least two Group VIB metals. The process comprises combining and reacting at least one Group VIII non-noble metal component with at least two Group VIB metal components in the presence of a protic liquid, with at least one of the metal components remaining at least partly in the solid state during the entire process. The Group VIII and Group VIB metals comprise from about 50 wt. % to about 100 wt. %, calculated as oxides, of the total weight of said bulk catalyst particles, with the solubility of those of the metal components which are at least partly in the solid state during the reaction being less than 0.05 mol/100 ml water at 18° C. The invention also covers a catalyst composition made by that process and a process for the hydroprocessing of a hydrocarbon feedstock by contacting the feedstock with that catalyst at hydroprocessing conditions.
