Abstract

We investigated the adsorption/desorption property of volatile organic compounds(VOC) by using activated carbon fibers(ACF) instead of activated carbon(AC) which is conventionally used. The adsorption behavior of the fixed bed and the breakthrough characteristics were also studied. As a result, ACFj showed 1.15 times higher adsorption amount as compared to AC. The breakthrough Point and adsorption amount of VOCs were decreased with the increase of temperature. In the case of AC, desorption time having 99% removal efficiency was about as minutes, but that of ACF was about 5 minutes at same condition.

기존에 주로 사용되었던 활성탄을 대체할 수 있는 활성탄소섬유를 이용하여 휘발성 유기화합물질의 흡 탈착 특성을 연구하였으며, 고정층을 이용하여 흡착 및 파과특성을 조사하였다. 활성탄소섬유중 ACFJ의 경우가 활성탄에 비하여 약1.15배 높은 흡착량을 보였으며, 흡착층의 온도가 증가함에 따라 파과시간 및 흡착량은 감소하였다. 또한 활성탄의 경우 약 99%까지 탈착하는데 20분이 소요되었으며, 활성탄소섬유의 경우 약 99% 탈착되기까지 5분이 걸려 활성탄소섬유가 약 4배 빠르게 탈착됨을 알 수 있었다.
