FIELD: carbon materials.
SUBSTANCE: invention relates to manufacture of activated carbons based on anthracite and process according to invention consists in treating starting material with hydrochloric acid and/or ammonia solution at 50-60°C followed by filtration, drying, and subsequent gradual (10-30°C/min) raise of temperature to 750-800°C to perform activation.
EFFECT: shortened manufacturing time, increased specific surface, adsorption capacity, and crushing resistance of activated carbon.
