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
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. 2. The process of claim 1, wherein the heavy feedstock is selected from the group consisting of vacuum residue, heavy crude, extra heavy crude and combinations thereof. 3. The process of claim 1, wherein the heavy feedstock is vacuum residue. 4. The process of claim 1, wherein the heavy feedstock has an API gravity of between about 1 and about 7. 5. The process of claim 1, wherein the heavy feedstock has a metal content of between about 200 and about 2,000 wtppm. 6. The process of claim 5, wherein the metal content of the heavy feedstock comprises vanadium and nickel. 7. The process of claim 1, wherein the catalyst emulsion comprises a first catalyst emulsion containing the group 8-10 metal and a second catalyst emulsion containing the group 6 metal. 8. The process of claim 1, wherein the group 8-10 metal is selected from the group consisting of nickel, cobalt, iron and combinations thereof. 9. The process of claim 1, wherein the group 6 metal is selected from the group consisting of molybdenum, tungsten and combinations thereof. 10. The process of claim 1, wherein the group 6 metal is in the form of a group 6 sulfide metal salt. 11. The process of claim 1, further comprising the steps of crushing and screening a raw coke to produce raw coke particles, and thermally treating the raw coke particles to produce the coke particles for use as the organic additive. 12. The process of claim 1, wherein the process produces the upgraded hydrocarbon at a conversion rate from the heavy feedstock of at least about 80 wt %. 13. The process of claim 1, wherein the hydroconversion produces an unconverted residue containing said solid carbonaceous material, and wherein said solid carbonaceous material from said unconverted residue has a carbon content of between about 85 and about 93 wt %. 14. The process of claim 1, wherein the solid carbonaceous material is in flake form. 15. The process of claim 1, wherein the process is carried out on a continuous basis. 16. The process of claim 15, wherein the process is carried out with the feedstock on a once-through basis. 17. The process of claim 1, wherein the hydroconversion conditions comprise a reactor pressure of between about 130 and about 210 barg, and a reactor temperature of between about 430 and about 470° C. 18. The process of claim 1, wherein the catalyst emulsion and the heavy feedstock are fed to the reactor in amounts to provide a ratio of catalyst metals to heavy feedstock, by weight, of between about 50 and about 1,000 wtppm. 19. The process of claim 1, wherein product yield on a weight basis, excluding the solid carbonaceous material, is greater than weight of the heavy feedstock. 20. The process of claim 1, wherein the solid carbonaceous material is fed to a metal recovery unit to separate the group 8-10 metal, the group 6 metal and the at least one feedstock metal. 21. The process of claim 1, wherein the upgraded hydrocarbon product comprises a vapor phase and a liquid-solid phase comprising the solid carbonaceous material and unconverted residue. 22. The process of claim 21, wherein the vapor phase is fed to a sequential hydroprocessing unit for further upgrading, and wherein the liquid-solid phase is fed to a vacuum flash tower for separation of remaining lighter materials from the unconverted heavy feedstock, and the solid carbonaceous material is fed to a metal recovery unit. 23. The process of claim 1, wherein the hydroconversion zone comprises an up flow co-current three-phase bubble column reactor. 24. The process of claim 23, wherein the organic additive is added in an amount between about 0.5 and about 5.0 wt % with respect to the heavy feedstock. 25. The process of claim 23, wherein the organic additive has a particle size of between about 0.1 and about 2,000 μm. 26. The process of claim 1, wherein the feedstock is derived from at least one of tar sand, bitumen, and combinations thereof. 27. The process of claim 1, wherein the feedstock is subjected to the hydroconversion conditions without any pretreatment.
