Abstract
고정층 반응기에서 활성탄 흡착제를 사용하여 질소 기류에서 벤젠 증기의 파과곡선을 측정하였다. 흡착실험은 흡착온도 25~50 ℃, 질소 가스의 유량 80~150 cm3/min, 흡착제의 공급량 3~5 g, 그리고 벤젠 증기의 농도는 포화조의 온도를 25~40 ℃로 변화시켜 행하였으며, 파과곡선의 비선형해석으로부터 비활성화 모델의 흡착속도상수와 비활성속도 상수를 구하고 비활성화 모델과 흡착 등온 모델과의 상관관계를 고찰하였다.
Activated carbon was used as an adsorbent to capture benzene vapor from gaseous stream of nitrogen in a fixed-bed to obtain the breakthrough data. The deactivation model is used to analyze the adsorption kinetics of benzene vapor using the experimental breakthrough data. The experimental breakthrough data are fitted very well to the deactivation model than the adsorption isotherm models in the literature.
