The Co-Mo catalysts have been prepared on laboratory scale by controlled impregnation of extruded γ-alumina with aqueous solutions of suitable active components, and their activity has been tested in the hydrodesulfurization and hydrogenation of aromatic compounds in gas oil. The kinetics of impregnation of the carrier, the effect of its nature, the order of impregnation of precursors of the individual active components, and the effect of their nature on the activity of the catalyst prepared have been studied. The samples prepared have been compared with selected commercial catalysts.
