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 3PO 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.
