A catalyst having utility as a downstream catalyst in processes for hydrodesulfurization of asphaltene-containing petroleum oils, coal liquids, shale oils or oils from tar sands which employ both upstream and downstream catalysts in series is described. The downstream catalyst comprises supported Group VI and Group VIII metals together with a promoting amount of a Group IV-B metal. The particles of the promoted catalyst are elongated extrudates whose surface is provided with a plurality of alternating longitudinal grooves and protusions. In processes using this catalyst, the upstream catalyst comprises Group VI and Group VIII metals without promotion with Group IV-B metal and the particles of the upstream catalyst may or may not have similar surface grooves. The adaptation of the grooved particle configuration to the promoted catalyst composition provided the early development of a plateau-like aging curve which was not achieved by the adaptation of the grooved shape to a non-promoted catalyst.
