The influence of DK coking additive from oil refining—specifically, the solid product from the slow coking of heavy petroleum residues—in coal batch on the quality of the coke produced is studied in laboratory conditions. In comparison with coal concentrates, DK coking additive is characterized by lower ash content (A d = 1.1%) and higher sulfur content (S t d = 3.7%); the yield of volatiles V daf = 18.2%. The DK coking additive is added to the batch in doses of 4.8%, 9.1%, and 13%, with proportional decrease in the batch components. In other cases, DK coking additive is added to the batch in doses of 10%, in place of coal of the clinkering and coke groups. Coke is produced from the batch in the laboratory. The coal charge is 2 kg; the piece size is ≤3 mm. With increase in the content of DK coking additive to 13%, the strength of the coke after reaction (CSR) increases linearly from 49.2 to 54.9%, while the reactivity CRI declines linearly from 37.9 to 33.8%. The improvement in coke quality is greatest when GZh coal (a clinkering component) is replaced by the DK additive: CSR rises to 59.2% and CRI falls to 30.8%. The most promising approach is to replace the scarcest and most expensive coal—OS coal (the coke group) and KS coal (the lean group)—with DK additive, with 3.8% increase in CSR and 3.3% decrease in CRI.
