Claim:
1. A process for upgrading heavy hydrocarbon mixtures comprising the steps of: a) separating the heavy hydrocarbon mixture into a light fraction, a full gasoil fraction and a vacuum residue fraction; b) adding a catalyst to the full gasoil fraction and subjecting the catalyst-full gasoil fraction to catalytic steam cracking to form an effluent stream; c) separating the effluent stream into a gas stream and a liquid stream; d) deasphalting the vacuum residue fraction from step a) to form a deasphalted fraction and an asphaltene-rich fraction; e) splitting the asphaltene-rich fraction from step d) into at least a first asphaltene-rich stream and a second asphaltene-rich stream, wherein the first asphaltene-rich stream is used as fuel; and f) mixing the liquid stream with the light fraction and the second asphaltene-rich stream to form an upgraded oil.
