Abstract

Adsorption characteristics of CO and $CO_{2}$ gases for a fixed-bed adsorber filled with 37wt% CuCl-impregnated activated carbon were measured. We found that the amount of equilibrium adsorption of $CO_{2}$ is less than that of CO on the adsorbent. Accordingly, the breakthrough point of $CO_{2}$ was reached earlier than the case of CO. As a result, we concluded that the adsorbent prepared in this work can possibly be used to selectively separate CO from the mixture of CO and $CO_{2}$ gases. Also, the experiment showed that the behavior of breakthroughs mainly depend on bed temperature and gas flowrate rater than the concentration of component to be adsorbed. Finally, a method that can calculate adsorption characteristics of the bed was proposed based on the theory of FH-VSM equilibrium isotherm. The calculated adsorption behaviors agree well with the experiment.

활성탄에 염화제1구리를 함침시킨(37wt%) 흡착 고정 흡착층에 대하여 일산화탄소 및 이산화탄소의 흡착 거동특성을 실험하였다. 그 결과, 흡착평형량이 작은 이산화탄소의 파괴점이 일산화탄소에 비하여 조기에 형성되므로 혼합가스로부터 일산화탄소의 선택적 분리가능성을 확인하였다. 각 성분의 파과거동은 흡착가스의 농도보다는 고정 흡착층의 온도와 흡착기체의 유속에 크게 영향을 받는 것으로 나타났다. FH-VSM 흡착평형 모델식을 근거로 고정 흡착층내 흡착거동 및 파과특성을 계산할 수 있는 방법을 제안하였다. 고정 흡착층 모델의 모사결과 실험으로부터 얻어낸 흡착특성을 비교적 정확히 해석할 수 있었다.
