제목 Effect of activation reagent on micropore structure of pitch-based activated carbon in physical activation
초록 In this study, the effect of the activation reagent on the pore structure of pitch-based activated carbon (AC) was investigated. The pitch based on petroleum residue was used as a raw material. The AC was prepared using CO2 or steam with N2 carrier under 900 °C. The activation time was 1 h with steam and varied from 1 to 5 h with carbon dioxide. It is noted that the pitch was oxidized by air before activation process. The pre-oxidation of pitch has a key factor to prepare microporous AC using CO2 as the activation reagent. It is strongly assumed that the surface chemical structure of carbon material affects the degree of activation due to the weak activation nature of CO2 activation. Finally highly microporous AC with high specific surface area was obtained from physical activation of pitch.
