CHARGE FOR METALLURGICAL COKE PRODUCTION Russian patent published in 2017 - IPC C10B57/04 

FIELD: metallurgy.

SUBSTANCE: charge is proposed for the metallurgical coke production. The charge contains, wt %: petroleum coke 30.0-1.0; oil residues 30.0-1.0; a mixture of coals of 40.0-98.0. The oil residues used are characterised by ash content of A^d not more than 2.5%, the yield of volatile substances of V^daf not more than 90%, sulfur content of S^d not more than 5%, Roga index (IR) no less than 10. Petroleum coke is characterised by ash content of A^d not more than 2.5%, the yield of volatile substances of V^daf not more than 25%, sulfur content of S^d not more than 5%.

EFFECT: expanding the functionality of the charge for coking by removing restrictions on the type of coal used in the charge.
