FIELD: oil processing. SUBSTANCE: method for production of petroleum coke includes supply of recirculate to raw material, heating of obtained mixture in tube furnace mixture coking in reactor of unit of slow coking. Introduced preliminarily into recirculate and/or in mixture of raw material with recirculate is air in the amount of 2-9 mas.% for raw material. EFFECT: improved quality of coke, higher yield of large-lump coke, reduced specific consumption of energy and increased overhaul period of the plant. 1 tbl
