METHOD OF PREPARING CRUSHED CARBONACEOUS ADSORBENT FROM POLYMER MATERIAL

摘要

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 150-170C and holding for 12-15 hours, crushing, carbonisation at 450-500C 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. ^ 3 ex
