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) an unsupported catalyst emulsion containing at least one group 8-10 metal and at least one group 6 metal, (c) hydrogen and (d)
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) an unsupported catalyst emulsion containing at least one group 8-10 metal and at least one group 6 metal, (c) hydrogen and (d) an organic additive to an upflow bubble column reactor defining a hydroconversion zone 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 comprises a solid organic material having a particle size of between about 0.1 and about 2,000 μm, a bulk density of between about 500 and about 2,000 kg/m3, a skeletal density of between about 1,000 and about 2,000 kg/m3 and a humidity of between 0 and about 5 wt %, and treating the solid carbonaceous material to recover said group 8-10, said group 6 and said at least one feedstock metals. 2. The process of claim 1, wherein the organic additive is present in an amount between about 0.5 and about 5 wt % with respect to the feedstock. 3. The process of claim 1, wherein the process has a gas velocity of greater than or equal to about 4cm/s. 4. The process of claim 1, wherein the hydroconversion exhibits an asphaltene conversion rate of at least about 75 wt % and a Conradson carbon conversion of at least about 70 wt %. 5. 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. 6. The process of claim 1, wherein the heavy feedstock is vacuum residue. 7. The process of claim 1, wherein the heavy feedstock has an API gravity of between about 1 and about 7. 8. The process of claim 1, wherein the heavy feedstock has a metal content of between about 200 and about 2,000 wtppm. 9. The process of claim 1, wherein the metal content of the heavy feedstock comprises vanadium and nickel. 10. 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. 11. The process of claim 1, wherein the group 8-10 metal is selected from the group consisting of nickel, cobalt, iron and combinations thereof. 12. The process of claim 1, wherein the group 6 metal is selected from the group consisting of molybdenum, tungsten and combinations thereof. 13. The process of claim 1, wherein the group 6 metal is in the form of a group 6 sulfide metal salt. 14. The process of claim 1, wherein the organic additive comprises coke particles. 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 upflow bubble column reactor comprises an upflow co-current three-phase bubble column reactor. 21. The process of claim 1, wherein the organic additive controls temperature in the hydroconversion zone by improving fluid-dynamics and reducing foam in the hydroconversion zone. 22. The process of claim 1, wherein the organic additive scavenges metals from the feedstock and the catalyst emulsion. 23. The process of claim 1, wherein the catalyst emulsion comprises a water-oil emulsion containing said at least one group 8-10 metal and said at least one group 6 metal in solution in an aqueous phase of the emulsion. 24. The process of claim 23, wherein the water-oil emulsion contains an oil phase which is different from the heavy feedstock. 25. The process of claim 1, wherein the particle size is between about 20 and about 1000 pm.
