Activation of pyrolytic rice husk char has been carried out using carbon dioxide as activation agent. The effect of activation time has been studied in a fixed bed reactor at 800 ºC. The char samples used in the activation process have been obtained by continuous flash pyrolysis carried out in a conical spouted bed reactor at 500 ºC. This char is mainly composed of carbon and ash present in the raw material (98 wt. %...
