In this study, the correlation between the pore characteristics of activated carbon fibers (ACF) and the noxious gas (methane and butane) adsorption capacity was studied. The ACF was prepared by various physical activation methods (Steam and CO2 activation). The textural properties of ACF were investigated using N2/77 K adsorption isotherms. The structural characteristics of the ACF were observed by X-ray diffraction and Raman spectroscopy. As a result, the specific surface area of activated carbon increased as the activation time increased. It was also observed that various pore size distributions were found to be dependent on the functions of the activation method and time. Increased activation time induced higher specific surface area and micropore volume, which resulted in higher noxious gas (methane and butane) adsorption capacity. |
