FIELD: petrochemical industry.
SUBSTANCE: invention refers to petrochemical industry, particularly to treatment of black oil in the process of delayed coking. The method of low-sulphur oil coke production is performed by means of delayed coking of a mixture consisting of petrochemical and/or oil processing black oil; at that 10-25% of a hydro refined gasoline fraction of liquid coke products, preliminary heated up to 200-300°C, is added into black oil or into the mixture.
EFFECT: invention facilitates production of a low sulphur coke implementing a low cost process due to a selection of a used mixture composition and due to excluding the stage of a coke hydrogen treatment under increased pressure.
