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.
Claims7
An improved hydrodesulfurization catalyst comprising particulate refractory porous inorganic oxide carrier material and a hydrogenation component, the improvement which comprises a diffusion limiting coating formed from a material selected from the group consisting of hydrated clays, hydrated silica, hydrated alumina and mixtures thereof on the catalyst particle exterior surfaces.
