FIELD: oil and gas industry.
SUBSTANCE: coke obtaining method involves heating of coking raw material in the furnace up to 480-500°C, introduction of inorganic additive to the coking raw material after it is heated in the furnace and further coking of the obtained mixture in the reactor; at that, inorganic additive is added to the coking raw material in the form of a paste-like mixture with hydrocarbon diluter. As inorganic additive there used is CaO or Ca(OH)2 or CaCO3. Hydrocarbon diluter represents initial coking raw material or heavy oil residues and other oil products.
EFFECT: method allows enlarging the furnace life and increasing the efficiency of slow coking plant.
