OSTI ID:5527452
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. Th method is characterized by subjecting a petroleum heavy oil or tar sand bitumen or crude shale oil heat treatment together with at least one additive selected from the group consisting of metal salt of dialkyldithiocarbamic acids, diaryldithiocarbamic acids, alkylxanthogenic acids, arylxanthogenic acids, dialkyldithiophosphoric acids, diaryldithiophosphoric acids, organic phosphoric acid esters benzothiazoles and disulfides.
