ABSTRACT OF THE DISCLOSURE: In a process of converting non-distillable resi- dues of mixed-base or paraffin-base crude hydrocarbon oils to distillable precursors for motor fuels and/or petro- chemical products by donor solvent hydrovisbreaking in the presence of donor solvent hydrovisbreaking, and of hydrogen, the required hydrogen donor solvent is produced in that part of the distillate produced by hydrobisbreaking is withdrawn and is catalytically treated in the presence of molecular hydrogen. In that treatment, aromatic compounds are converted to naphthenic compounds by a selective catalytic hydrogenation and paraffins are converted to naphtha fractions boiling below the boiling range of the hydrogen donor solvent by a selective catalytic cracking. The selective hydrogenation catalysts which are used consist preferably of Ni or Mo catalysts. The selective cracking catalysis which are used consist preferably of molecular sieves, such as zeolites or Silicalites.
