METHOD OF PRODUCING ACTIVATED CARBON Russian patent published in 2015 - IPC C01B31/08 C01B31/14

Abstract RU 2565202 C1

FIELD: chemistry.

SUBSTANCE: activated carbon is produced using a mixture of coal-based carbon and a water-bitumen emulsion with 50-70% binder content. Granulation is carried out through a draw plate with hole diameter of 1.0-5.0 mm at pressure of 70-250 kg/cm². Heat treatment is carried out in the temperature range of 250-350°C in the presence of air. Carbonisation is carried out, followed by activation in a steam medium.

EFFECT: obtaining granular activated carbon with improved sorption and strength properties, which can be used in treatment of gases, vapour and liquids.
