Preparation of activated carbon from chicken waste is a promising way to produce a useful adsorbent for Hg removal.A three-stage activation process (drying at 200℃,pyrolysis in N2 atmosphere,followed by CO2 activation) was used for the production of activated samples.The effects of carbonization temperature (400-600 ℃),activation temperature (700-900 ℃),and activation time (1-2.5 h) on the physicochemieal properties (weight-loss and BET surface) of the prepared carbon were investigated.Adsorptive removal of mercury from real flue gas onto activated carbon has been studied.The activated carbon from chicken waste has the same mercury capacity as commercial activated carbon (Darco LH) (HgV:38.7% vs.53.5%,HgO:50.5% vs.68.8%),although its surface area is around 10 times smaller,89.5 m2/g vs.862 m2/g.The low cost activated carbon can be produced from chicken waste,and the procedure is suitable.
