A combination slurry hydroconversion, coking and coke gasification process is provided wherein solid fines having an average particle size of less than 10 microns in diameter or the ashes thereof recovered from a gaseous product derived from the coke gasification are used as a catalyst in the hydroconversion stage in combination with a catalyst produced from an oil soluble metal compound in situ in the chargestock of the hydroconversion zone.

A process for upgrading a carbonaceous chargestock, which comprises: (a) adding to said carbonaceous chargestock an oil soluble metal compound of a metal selected from the group consisting of Groups IVB, VB, VIB, VIIB and VIII of the Periodic Table of Elements and mixtures thereof; (b) converting said oil soluble metal compound to a solid catalyst within said chargestock in the presence of a hydrogen-containing gas by heating said chargestock to an elevated temperature; (c) reacting the chargestock containing said catalyst with hydrogen under hydroconversion conditions, in a hydroconversion zone to produce an upgraded hydrocarbonaceous oil product; (d) separating a heavy oil fraction from said hydrocarbonaceous oil product; (e) contacting at least a portion of said heavy oil fraction with a bed of fluidized solids maintained in a fluid coking zone under fluid coking conditions to form coke, said coke depositing on said fluidized solids; (f) introducing a portion of said solids with a coke deposit thereon into a heating zone operated at a temperature greater than said coking zone temperature to heat said portion of solids; (g) recycling a first portion of heated solids from said heating zone to said coking zone; (h) introducing a second portion of said heated solids to a fluid bed gasification zone maintained at a temperature greater than the temperature of said heating zone; (i) reacting said second portion of heated solids in said gasification zone with steam and a molecular oxygen-containing gas to produce a hot gaseous stream containing hydrogen; (j) introducing said hot gaseous stream containing hydrogen and entrained solids into said heating zone; (k) recovering from said heating zone the resulting cooled gaseous stream containing hydrogen and entrained solid carbonaceous fines; (l) separating at least a portion of said solid carbonaceous fines from said cooled gaseous stream, said separated fines having an average particle size of less than 10 microns in diameter, and (m) recycling at least a portion of said separated fines to such chargestock of step (a).
