POROUS CARBON MATERIAL, METHOD FOR PRODUCTION THEREOF, ADSORBENTS, MASKS, ABSORBENT SHEETS AND CARRIERS Russian patent published in 2013 - IPC C01B31/08 B01J20/20 A61K33/44 

FIELD: chemistry.

SUBSTANCE: invention relates to carbon materials. Described is a method of producing porous carbon material from silicon-containing plant material. The method involves carbonising plant material by temperature treatment, treating with acid or alkali, followed by activation. The porous carbon material has nitrogen BET specific surface area of at least 130 m²/g, mesopore and micropore volume of at least 0.1 cm³/g, measured by BJH method and MP method and containing more mesopores smaller than 20 nm than mesopores having size of at least 20 nm. The obtained material is used, for example, as an adsorbent, an adsorbent for oral administration, a medical adsorbent, a creatinine adsorbent, a cap for blood purification columns, a water treatment adsorbent, a mask, an adsorbent sheet, a medicine carrier and a carbon-polymer complex.

EFFECT: invention enables to obtain material with a wide range of applications.
