FIELD: process engineering.
SUBSTANCE: invention relates to production of active coals and may be used for land reclamation and feed detoxication. Proposed method comprises mincing batch mixture consisting of 75-85% of black coal and 25-15% of coal char, mixing with coal char resin, pelletising, drying, carbonising and activation. Carbonising is carried at two stages, i.e. first at 420-460°C and, then, at 720-760°C.
EFFECT: increased high-molecular organic substance absorption capacity.
