ABSTRACT:
A spent hydrotreating catalyst composition is regenerated by a two-step heating process under such conditions as to substantially remove all carbonaceous deposits therefrom and to increase the average pore diameter of the catalyst composition. The thus-prepared regenerated catalyst composition is employed in a process for hydrotreating metal-containing oils.
