ABSTRACT:
Heavy hydrocarbon oil to be processed is subjected to a treatment at elevated temperature and superatmospheric pressure in the presence of dispersed solids and molecular hydrogen and recycled hydrogen donor oil. By this treatment, a certain part of the asphaltenes absorbed on the solids may be coked. The product of that donor solvent hydrovisbreaking (DSV) is distilled. The distillate or distillates is or are catalytically hydrogenated. The visbreaking residue is used for the production of hydrogen. The hydrogenated products are separated in hydrocarbon fractions and are then processed further to fuels and/or petrochemical products and a part of the hydrogenated products is recycled as inherent donor solvent.
