A method is provided for producing cracked oil with a higher yield and coke having a higher fixed carbon content from petroleum heavy oil or tar sand bitumen or crude shale oil in a short time. This method is characterized by subjecting a petroleum heavy oil or tar sand bitumen or crude shale oil to heat treatment together with at least one additive selected from the group consisting of metal salts of dialkyldithiocarbamic acids, diaryldithiocarbamic acids, alkylxanthogenic acids, arylxanthogenic acids, dialkyldithiophosphoric acids, diaryldithiophosphoric acids, organic phosphoric acid esters, benzothiazoles and disulfides.

A method for producing cracked oil and homogeneous coke of higher fixed carbon with a higher yield by treating petroleum heavy oil selected from the group consisting of atmospheric residue, vacuum residue, thermally-cracked residue, catalytically cracked residue, solvent deasphalted residue, tar sand bitumen and crude shale oil, which comprises subjecting said petroleum heavy oil to heat treatment at a temperature of 400°-550°C. by continuously feeding an additive selected from the group consisting of zinc, nickel, tin, lead, cadmium, tungsten and molybdenum salts of dialkyldithiocarbamic acid, diaryldithiocarbamic acid, alkylxanthogenic acid and arylxanthogenic acid to said petroleum heavy oil.
