FIELD: technological processes.
SUBSTANCE: invention concerns chemical technology, particularly sorbent production for elimination of oil products from industrial sewage, and can be applied in power engineering, metallurgy, chemical technology, mining and other industrial fields. Method of obtaining carbon sorbent involves brown coal grinding into 0.5-5 mm fraction, heating to 150-300°C, maturing at this temperature for 2-5 hours with continuous withdrawal of gases exuded during heating, and cooling down.
EFFECT: reduced power input for obtaining carbon sorbent with high sorption properties.
