Activated carbon (AC) was prepared from oil palm shell using different ratios of KOH as an activation agent and various microwave irradiation powers. To study the effects of physical agents, the impregnated precursors were activated under a flow of CO2 or N-2. Maximum BET surface areas of 1196 and 1630 m(2)/g were achieved in the presence of CO2 and N-2, respectively. The textural properties of the samples with the highest surface areas were investigated using ultimate and proximate analyses, SEM and FTIR. The CO2 adsorption results suggest that the ACs are promising adsorbents for gas separation or storage applications. (C) 2014 The Korean Society of Industrial and Engineering Chemistry.
