FIELD: coke industry. SUBSTANCE: raw material is dried, heated for 10-120 s in gas heat carrier flow to 500-650 C, conditioned 10-40 min in non-heated chamber to produce semicoke and steam-gas mixture. Semicoke is subjected to steam-gas activation. EFFECT: improved adsorption properties of product and decreased amount of dust-like fractions.
