ABSTRACT A process is provided for converting a heavy hydrocarbon oil into light hydrocarbon fuels by thermal cracking or hydrocracking, which comprises ; to about 100 parts by weight of the heavy hydrocarbon oil feedstock (A) being added about 0.1 to 50 parts by weight of a substance (B) selected from any one of the following (I) and (II), wherein (I) are hydrogen-donor substances each of which comprises a hydrogenated oil obtained by aromatic ring hydrogenation of a thermal-cracked product oil boiling higher than about 200°C, said aromatic ring hydrogenation being conducted so as to hydrogenate about 20 to 90 % of the aromatic rings present in the product oil, said thermal cracking being conducted at about 430 to 600°C by using a petroleum feedstock, and (II) are hydrogen-donor substances each of which comprises a hydrogenated oil obtained by aromatic ring hydrogenation of a thermal-treated product oil boiling higher than about 200°C, said aromatic ring hydrogenation being conducted so as to hydrogenate about 20 to 90 % of the aromatic rings present in the product oil, said thermal treating being conducted at about 430 to 600°C by using a catalytic-cracked or catalytic-reformed product boiling higher than about 200°C, said catalytic cracking or catalytic reforming being conducted by using a petroleum feedstock.
