METHOD FOR PRODUCTION OF ACTIVATED CARBON Russian patent published in 1997 - IPC

Abstract RU 2073643 C1

FIELD: production of activated carbon. SUBSTANCE: shells of coconut are ground, carbonized by heating at decreased pressure, activated by carbon dioxide, cooled by quenching agent and suspension is prepared in water being saturated with carbon dioxide. Mentioned above activation takes place at statistic discharge by simultaneous affection by electric potential at 0.1-0.5 V. Said suspension is prepared at simultaneous cyclic affection of impact pressure at (10-20)109 Pa and alternative electric potential at (20-50)103 V. EFFECT: improved efficiency. 1 tbl
