FIELD: chemistry.
SUBSTANCE: invention relates to method of obtaining active coal. Method includes separation of 1-3 mm fraction from charge for layered high-temperature coking and the following stages: oxidation with air oxygen at temperature 250°C with rate of temperature increase from room to specified temperature 15-20°C/min with keeping at final temperature for 2.5 hours, carbonisation of oxidised raw material with temperature increase with rate 5°C/min to temperature of carbonisation 550-650°C, with keeping at temperature of carbonisation for 60 minutes, and activation of obtained products with water steam to 35-40% burn at temperature 950°C.
EFFECT: providing possibility of obtaining active coals from charges of coking production without introduction of any additional components.
