FIELD: chemistry.
SUBSTANCE: method includes mixing coffee cake, formed in the process of instant coffee production, with condensed pyrolysis resins, which have carbon content higher than 65%, and carbonised material, which has content of carbon over 80%. Mixture is granulated, dried and subjected to pyrolysis. Part of formed pyrolysis resins is returned to stage of mixing. Carbonisation is realised. One part of carbonised material is returned to stage of mixing and the other part of carbonised material is supplied to activation by water steam with obtaining target product. Mixing of initial components is realised in such a way, that the total content of carbon in granulated mixture constitutes not less than 55%.
EFFECT: obtaining of coal with high sorption activity.
