    Abstract: A catalytic slurry process for effecting the conversion of a hydrocarbonaceous charge stock containing asphaltenes, metallic contaminants and excessive quantities of sulfurous compounds. The slurry constitutes the charge stock, hydrogen and from about 1.0 percent to about 25.0 percent by weight of finely divided catalyst particles. The charge stock is converted by processing the slurry in at least two individual reaction zones having separation facilities therebetween. That portion of the first reaction zone product effluent containing the catalyst particles and unconverted nondistillables is processed in a succeeding reaction zone. At least the major portion of the product effluent from the succeeding reaction zone is recycled to combine with the fesh feed charge stock. Preferred catalysts are the unsupported sulfides of the metals from Groups V-B, VI-B and VIII.
