FIELD: chemistry.SUBSTANCE: invention relates to technological processes of obtaining wood-based active coal. Method of obtaining activated coal lies in drying, carbonisation and activation of raw material in reactor and in further discharge of obtained product. As raw material used is wood chips with particle size from 1 mm to 10 mm and initial humidity from 30% to 70%. Drying, carbonisation and activation are carried out with straight flow movement of chips through reactor with rate of temperature rise in it 20-80°C/min to pyrolysis temperature 800-900°C, at which air is supplied into reactor.EFFECT: invention ensures obtaining coal with high sorption iodine activity.2 cl, 9 ex |
