ABSTRACT:
Heavy hydrocarbonaceous oil is cracked by hydrogen donor diluent cracking, and pitch from the donor cracking step is recycled. The pitch is catalytically hydrotreated before it is recycled. Hydrotreating the pitch enables complete conversion of the 950.degree. F.+ fraction of heavy hydrocarbonaceous oil to 950.degree. F.- distillate.
