The production of petroleum coke from heavy oil tar and from asphalt (derived from heavy oil tar by means of propane) at excess pressures of 0.15, 0.25, and 0.35 MPa is considered. The influence of the coking pressure on the physicochemical properties (moisture content, ash content, yield of volatiles, etc.) of the resulting petroleum coke is studied. The coke from heavy oil tar is compared with the coke from asphalt in terms of quality. The petroleum coke meets all the requirements in State Standard GOST 22898–78. Its moisture content is no more than 3.0%; its yield of volatiles is no more than 6–8%; and its ash content is no more than 0.30–0.80%.
