METHOD OF REGENERATION OF ACTIVATED CHARCOAL Russian patent published in 2001 - IPC

Abstract RU 2167103 C1

FIELD: adsorption equipment, more particularly charcoal adsorption processes for purifying liqueurs and vodkas, drinking water, sewage, recuperation of volatile solvents. SUBSTANCE: method comprises heating charcoal to 660-700 C at temperature rise rate of 30-60 C/min, treatment with steam at steam to charcoal weight ratio of (2-4):1 and cooling of charcoal in atmosphere containing no oxygen at temperature rise rate of 60-100 C/min. Method makes it possible to recover fully adsorption properties of charcoal spent in liqueur-vodka industry, thus making it possible to it many times. EFFECT: more efficiency regeneration method. 3 tbl
