ABSTRACT:
Metal poisoning of hydrodesulfurization catalysts is reduced by coating the catalyst surface with a hydrated clay mineral, hydrated alumina, hydrated silica, or mixtures thereof. The catalyst and process in which it is used are particularly useful for the desulfurization of residual oils to produce low-sulfur, fuel oil products.
