Abstract:
1. A hydroconversion process, comprising feeding (a) a heavy feedstock containing at least one feedstock metal selected from the group consisting of vanadium and nickel, (b) a catalyst emulsion comprising a water-oil emulsion containing at least one group 8-10 metal and at least one group 6 metal in solution in an aqueous phase of the emulsion, (c) hydrogen and (d) an organic additive to a hydroconversion zone of an upstream bubble column reactor under hydroconversion conditions to produce an upgraded hydrocarbon product and a solid carbonaceous material containing said group 8-10 metal, said group 6 metal, and said at least one feedstock metal, wherein the organic additive which has an anti-foaming effect comprises coke particles having a particle size of between about 0.1 and about 2,000 μm wherein the organic additive, and hydrogen are added to the heavy feedstock to provide a reactant blend which is fed to a heater prior to being fed to the hydroconversion zone, wherein the coke particles scavenge metals in the reactor and thereafter the coke particles with metals are passed from the reactor to a metal recovery station.
