A catalytic asphaltene-containing oil hydrodesulfurization process is described employing a fixed catalyst bed comprising particles of supported Group VI and Group VIII metals, preferably together with a separate and downstream fixed catalyst bed comprising particles of Group VI and Group VIII metals together with a promoting amount of Group IV-B metal. The catalyst particles in both beds are in the form of elongated extrudates whose surface is provided with a plurality of alternating longitudinal grooves and protrusions. An advantageous mass velocity-related catalyst activity effect is achieved by recycling a portion of the desulfurized liquid product.
