FIELD: technological processes.
SUBSTANCE: invention relates to preparation of activated carbon. The invention discloses a method of preparing crushed carbonaceous adsorbent from polymer material, involving mixing furfural with epoxy resin and sulphuric acid, hardening by heating the composition to 150-170°C and holding for 12-15 hours, crushing, carbonisation at 450-500°C and activation.
EFFECT: method enables to obtain low-ash adsorbents with high adsorption capacity on high molecular weight contaminants which are hard to remove and with high electric capacity.
