ABSTRACT OF THE DISCLOSURE: Heavy hydrocarbon oil to be processed is subjected to a treatment at elevated temperature and superatmospheric pres- sure in the presence of dispersed solids, molecular hydrogen and recycled hydrogen donor oil. By this treatment, a certain part of the asphaltenes adsorbed on the solids is coked. The product of that donor solvent hydrovisbreaking (DSV) is dis- tilled. The distillate or distillates is or are catalytically hydrogenated. The visbreaker residue is used for the production of hydrogen. The hydrogenated products are separated in hydro- carbon fractions and are then processed further to fuels and/ or petrochemical products.
