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.
In a slurry hydroconversion process comprising at least two zones, wherein heavy hydrocarbonaceous oil is converted to lower boiling products, which process comprises the steps of: (a) adding a catalyst or a catalyst precursor to a chargestock comprising a first portion of fresh heavy hydrocarbonaceous oil comprising at least 10 wt.% of materials boiling above about 1050°F., to form a mixture; (b) reacting the resulting mixture with a hydrogen-containing gas in a first hydroconversion zone operated at a temperature ranging from about 800°F. to about 900°...
