FIELD: chemical technology.
SUBSTANCE: method for producing a carbon sorbent is presented, including thermal-oxidative treatment of a layer of coal with a particle size of 1 mm to 30 mm in a vertical shaft-type apparatus with air supplied through it from the side opposite to the ignition side of the coal layer, characterized in that the coal is dried before the thermal-oxidative treatment process to humidity ranging from 0% to 40%.
EFFECT: increased productivity of a one-stage process for obtaining a sorbent with partial gasification of coal in a stationary layer, as well as increased adsorption activity for iodine of sorbents obtained at low specific air consumption, including from low-grade coals.
