PROCESS FOR MANUFACTURE OF ACTIVATED CARBON Russian patent published in 1995 - IPC

Abstract RU 2036141 C1

FIELD: chemistry. SUBSTANCE: this process prescribes admixing in water phenol, formaldehyde, water-soluble furan compounds (10 to 20 percent by mass) in presence of catalyst and emulsifier, washing and filtering thus prepared polymer suspension, thermally solidifying resultant polymer stock by heating it at temperature of 270 to 280 C at temperature building-up rate of 10 to 15 C/h, carbonizing end product, and finally activating it. EFFECT: more advanced technique. 1 tbl
