POWDERED ACTIVATED CARBON PRODUCTION PROCESS Russian patent published in 2000 - IPC

Abstract RU 2154605 C1

FIELD: carbon materials. SUBSTANCE: invention relates to production of activated carbon useful in drinking water treatment and can be used in chemical- pharmaceutical and food industries. Carbon-containing material is ground at grinding apparatus filling factor 0.05-0.10 and ground carbon is granulated with binding agent to give granules with content of volatiles 26-38%. Wet granules are partially dried with heating rate 2-5 C/min to temperature 40-50 C and then carbonized at 650-800 C in medium composed of fuel combustion products, activated, and ground to powder form. EFFECT: increased adsorption capacity regarding crude water organics. 3 ex
