This patent describes a hydrotreating process comprising the step of contacting a substantially liquid hydrocarbon-containing feed stream, which also contains compounds of at least one metal and/or sulfur as impurities, with a free hydrogen containing gas and a catalyst composition, under such conditions as to produce a hydrocarbon-containing stream having reduced levels of the at least one metal and sulfur; wherein the catalyst composition has been prepared by a process comprising the steps of (A) impregnating a support material comprising alumina with a solution consisting essentially of water and at least one dissolved thiocyanate compound; (B) heating the material obtained in step (A) under such conditions as to at least partially dry the material obtained in step (A); (C) impregnating the at least partially dried material obtained in step (B) with a solution comprising a liquid solvent and at least one dissolved compound of at least one metal selected from the group consisting of transition metals belonging to Group VB, VIB, Group VIIB, Group VIII and Group IB of the Periodic Table of Elements; (D) heating the material obtained in step (C) at a first temperature so as to least partially dry the material obtained in step (C); and (E) heating the at least partially dried material obtained in step (D) at a second temperature, which is higher than the first temperature, so as to activate at least partially dried material obtained in step (D).
