FIELD: chemistry.
SUBSTANCE: polycarbonate pyrolysis is carried out in a medium of coal-tar pitch with a ratio of polycarbonate: coal-tar pitch, equal (1.5-4.0):10.0 in an interval of temperatures of 350-380°C. A solid residue of the pyrolysis is subjected to chemical activation by its thermal processing in a mixture with an alkali metal hydroxide.
EFFECT: increased output of the product with high sorption characteristics.
