Characterization of Activated Carbon Prepared from Chicken Waste and Coal

摘要

Activated carbons (Acs) were prepared from chicken waste (CW) and coal (E-coal) blended atthe ratios of 100:0, 80:20, 50:50, 20:80, and 0:100, respectively. The process included carbonization inflowing gaseous nitrogen (300 mLmin-1) at ca 430oC for 60 minutes and successive steam activation(0.1mL min-1 water injection with a flow of N2 at 100mLmin-1) at 650 oC for 30 minutes. Chickenwaste is low in sulfur content but is high in volatile matter (approx. 55 wt%), and Acs with higherspecific surface area were more successfully obtained by mixing with coal. The specific surface area ofthe CW/Coal blend AC can be estimated by SSABET = -65.8x2 + 158x + 168, where SSABET is thespecific surface area in m2/g as determined by BET method using CO2 as the adsorbent, where x is thecoal fraction by weight (x = 0 – 1).
