METHOD OF PREPARING CRUSHED ACTIVATED CARBON FROM NUTSHELL Russian patent published in 2004 - IPC

Abstract RU 2228293 C1

FIELD: carbon materials. SUBSTANCE: invention relates to technology of preparing activated carbon suitable for drinking water treatment, in water treating processes, in medicinal and food industries, and also as support for catalytic additives. Method comprises carbonization of nutshell, heat treatment at 780-850 C for 15-24 h, activation of still hot carbon by heating it to 920-1050 C with water steam consumed in amount 8.5-12.0 kg per 1 kg activated carbon. EFFECT: improved adsorption capacity characteristics in water media treatment to remove ammonia. 3 ex
