FIELD: chemistry.
SUBSTANCE: invention relates to field of obtaining ferromagnetic carbon sorbents, intended for water purification. Cellulose-containing raw material is impregnated with water solution of iron salt, moisture excess is separated and obtained mixture is subjected to pyrolysis. Pyrolysis is carried out in pyrolysis chamber at 400-500°C, realising a series of successive 0.1-1.0 s long heat impulses with 10 s interval between impulses. Mixture heating is realised by means of nichrome rods, connected with electric generator and placed in the volume of pyrolysis chamber with separation of chamber into locally heated cells.
EFFECT: invention provides reduction of energy consumption, time for the process realisation and its cheapening.
