Microporous carbons prepared from African palm shells by carbonization and KOH activation were examined as adsorbents for CO2 capture. The micropore volume and specific surface area of the resulting carbons varied from 0.16 cm(3)/g (365 m(2)/g) to 0.82 cm(3)/g (1890 m(2)/g), respectively, depending on the KOH/char ratio used in the activation process. These carbons showed high CO2 adsorption capacities at 1 bar pressure reaching 4.4 and 6.3 mmol/g at 25 and 0 degrees C, respectively. (C) 2013 Elsevier Ltd. All rights reserved.
