Abstract
Activated carbon fibers(ACFs) were prepared in this research from a polyacrylonitrile(PAN) precursor with the KOH(1~4 M) pretreatment and following activation at 800oC in a lab-scale. The sample ACFs were characterized according to their textural properties, and evaluated for CO2 adsorption capacity. The surface area and pore volume of ACFs increased according to the pretreatment with KOH; for example, 4M-KOH aqueous solution resulted in 1552.5 m2/g specific surface area and 0.605 cc/g pore volume. It also showed high CO2 adsorption amount(3.11 mmol/g) which showed a proportional increase with reaction pressure.
