FIELD: process engineering.
SUBSTANCE: invention relates to carbon adsorbents. This invention covers the method of stabilising activated and/or cleaned oil shale by recirculation extraction by demineralised water heated to 40°-130°C. Raw shale is pretreated by steam or basic inorganic compound.
EFFECT: stable adsorbent for adsorption of organic and inorganic contaminants.
