PURPOSE:To economically and effectively hydrogenate a heavy oil, by deasphalting a heavy oil with a solvent, mixing the treated heavy oil with a light oil at a specific ratio and hydrogenating the mixture under a specific condition. CONSTITUTION:A heavy oil is deasphalted with a solvent and the deasphalted oil is mixed with a light oil in such a manner as to keep a Conradson carbon residue to <=5wt.%. The obtain mixture is subjected to hydrogenation treatment under hydrogen partial pressure of 30-60kg/cm<2> at a reaction temperature of 350-450 deg.C and an LHSV of 0.1-3.0/hr using a heavy oil-treatment catalyst. The heavy oil can be hydrogenated by this process. The catalyst is preferably produced by supporting a group VIA metal (e.g. Mo) and/or a group VIII metal (e.g. Co) on a carrier such as alumina and silica alumina.
