PROCESSING OF RICE WASTES INTO ACTIVATED CARBON

Abstract

A method for processing of rice wastes (husk, straw) into activated carbon was proposed. The thermolysis of raw material and the activation of carbonizate were carried out at 500ºС and 800ºС temperatures respectively. The properties of obtained activated carbon are determined by standard methods. The porous structure of obtained carbon have been studied under scanned electronic microscope. According to the results of experimental studies, activated charcoal obtained from rice husks corresponds to the WAC brand, activated charcoal obtained from rice straw corresponds to BAU-A grade. The research will allow rational use of agricultural waste in order to obtain useful secondary adsorbent products intended for adsorption and liquid media.
