Activated carbon (ACs) was produced by chemical activation of industrial furfural production waste (FPW) by different chemical activators. The carbon (HP‐AC500) produced from pyrolysis of H 3 PO 4 ‐FPW at 500 °C is microporous carbon with certain proportion of mesopores whose Brunauer‐Emmett‐Teller (BET) surface area and pore volume could reach 751.8 m 2 /g and 0.63 mL/g, respectively. The carbon (ZN‐AC600) produced from pyrolysis of ZnCl 2 ‐FPW at 600 °C is essentially microporous carbon whose BET surface area and pore volume could reach 1143 m 2 /g and 0.61 mL/g, respectively. ZN‐AC600 carbon shows better performance in adsorbing phenol with its maximum monolayer adsorption capacity reaching 166 mg/g, while HP‐AC500 carbon shows its better performance in adsorbing Cr (VI) with maximum monolayer adsorption capacity reaching 27 mg/g. The adsorption model based on Unilan together with Clausius‐Clapeyron equation provides a satisfactory representation for low‐pressure CO 2 , CH 4 , N 2 adsorption on ZN‐AC600 and HP‐AC500, respectively. Both equilibrium and kinetic results show that the HP‐AC500 carbon has better CO 2 separation performance. Copyright © 2011 Curtin University of Technology and John Wiley & Sons, Ltd.
