Abstract:
A slurry catalytic hydroconversion process comprising at least two hydroconversion zones is provided in which the heavy hydrocarbonaceous fresh oil feed is added to more than one hydroconversion zone. Additional portions of catalysts or catalyst precursors are also added to the first hydroconversion zone and to additional hydroconversion zones wherein said additional hydroconversion zones are maintained at a temperature of at least 10.degree. F. higher than an immediate preceding hydroconversion zone.
