A process for the hydroprocessing of heavy oils and/or oil residues, the process comprising the step of contacting the heavy oils and/or oil residues with a non-metallised carbonaceous additive in the presence of a hydrogen-containing gas at a temperature of from 250°C to 600°C, wherein at least 80% of the cumulative pore volume of the non- metallised carbonaceous additive arises from pores having a pore size of at least 2nm, wherein at least 50% of the cumulative pore volume of the non-metallised carbonaceous additive arises from pores having a pore size of at least 5nm, and/or wherein at least 30% of the cumulative pore volume of the non-metallised carbonaceous additive arises from pores having a pore size of at least 10nm. |
