Abstract: PURPOSE:To improve heat efficiency of process and to efficiently improve light oil fraction yield by adding a hydrogen donative solvent to a heavy oil fraction and subjecting the fraction to hydrogenolysis reaction in the presence of a hydrogenating catalyst under a specific condition. CONSTITUTION:A hydrogen donative solvent such as tetralin, dihydroanthracene or dihydropyrene is added to a heavy oil fraction such as petroleum, tar sand bitumen or shale oil and subjected to hydrogenolysis reaction in the presence of a hydrogenating catalyst at 400-460 deg.C (preferably 420-450 deg.C) under 100-300kg/ cm G (preferably 100-200kg/cm G) hydrogen pressure to give a light oil fraction.
