METHOD OF PRODUCTION OF GLOBULAR CARBON ADSORBENT

FIELD: production of activated carbon for medicine, production of drugs and high-purity agents; thorough cleaning of gaseous and liquid media from low-molecular, medium-molecular and high-molecular admixtures. ^ SUBSTANCE: proposed method includes mixing of thermoreactive organic liquids and hardening catalyst, forming spherical granules at viscosity of 10-30 cSt heated to 90-120°C, hardening of spherical granules and separation of them from oil, carbonization and vapor-and-gas activation of granules and their screening-out. Time of presence of spherical granules in heated oil during which they undergo gelatinization and poly-condensation stages is 10-30 s, after which spherical granules are kept under layer of oil for 2-10 h till complete hardening. Carbonization is performed in carbon dioxide medium at temperature of 650-850°C at rate of 6-10°C/min. Vapor-and-gas activation is performed at temperature of 850-950°C. Proposed method makes it possible to control parameters of activated carbon of micro-, meso- and macro-structure. ^ EFFECT: possibility of producing activated carbon possessing high adsorption ability to admixtures containing gaseous and liquid media. ^ 4 cl, 3 ex
