CHARGE FOR PRODUCING METALLURGICAL COKE Russian patent published in 2024 - IPC C10B57/04 C10B57/14 C10B55/00 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to coke-chemical industry, namely to composition of charge for production of metallurgical coke and to its application for production of metallurgical coke. Mixture contains a mixture of coal, an oil sintering additive and oil coke. Coal mixture contains sintering coals, coke coals, lean coals, oil sintering additive is a product of processing heavy oil residues, having the following characteristics: caking index G (1:5) is not less than 70, softening (melting) temperature, “КиС”, T is 95–125 °C, weight fraction of water W is less than 4%, weight fraction of total sulphur is less than 4%. Ratio of components in the charge is, wt.%: sintering coals 10.0–22.0, coke coals 5.0–20.5, lean coals 37.5–58, an oil sintering additive 1.0–25.0, petroleum coke 5.0–10.0.

EFFECT: obtaining a charge for coking of a special composition, which enables to expand and reduce the cost of the raw material base of the charge used without reducing or improving the quality of metallurgical coke, reduced ash content of coal charge and produced coke, increased sintering properties of charge, reduced content of sulphur, easier transportation of additive and reduced power consumption for coking.
