FIELD: chemistry.
SUBSTANCE: invention relates to highly efficiency adsorbents based on highly porous activated carbon with meso- and macropores, having the form of separate grains of activated carbon, where at least 55% of the total pore volume of the highly efficient adsorbents comprises pores (i.e. meso- and macropores) with diameter greater than 20 Ǻ, the adsorbents being characterised by pore diameter distribution centre greater than 25 Ǻ, having BET specific surface area of at least 1250 m2/g, iodine number 1250-2100 mg/g, and obtained from granules of sulphonated divinylbenzene-cross-linked polystyrenes via carbonisation or two-step activation.
EFFECT: invention enables to obtain adsorbents which, besides properties given above, have resistance to abrasive wear and destruction, and are suitable for use in various fields.
