ABSTRACT:
A process is described for hydrotreating residual oil fractions in an improved dual bed catalyst system comprising a first large-pore catalyst and a second small-pore catalyst in which at least the second catalyst and preferably both catalysts have a quadrulobal shape. Using cobalt and molybdenum composited on alumina as these catalysts, residua are demetalized, desulfurized, and reduced in carbon residue, whereby hitherto unusable residue can be hydroprocessed.
