Adsorption Equilibrium of CO and CO₂ on Activated Carbon Impregnated with Cuprous Chloride

초록

일산화탄소를 분리하기 위하여 제조한 염화제1구리-활성탄 흡착제에 대한 일산화탄소 및 이산화탄소의 흡착평형 실험을 수행하여 일산화탄소 및 이산화탄소의 각 성분에 대한 흡착평형 등온식을 얻었으며, 실험결과로 계산된 매개변수를 이용하여 각 흡착계를 FH-VSM흡착식으로 표현할 수 있었다. 또한 염화제1구리의 함침농도가 37%까지 증가함에 따라 일산화탄소의 흡착량이 증가하였으나 그 이상의 함침농도에서는 일산화탄소 흡착량이 감소하는 것으로 나타났으며, 이들 흡착제는 가열에 의한 탈착으로 반복사용이 가능하고 흡착 재현성이 우수하므로 TSA 공정용으로의 이용 가능성이 확인되었다.

Activated carbons impregnated with cuprous chloride were prepared to separate carbon mono-xide from gas mixture. Adsorption equilibrium experiments were performed for carbon monoxide and carbon dioxide. From these experimental results, adsorption equilibrium isotherms were obtained for each adsorption system. Each adsorption systems can be represented by FH-VSM adsorption equations with the parameters obtained from the experimental result. Amount of carbon monoxide adsorbed on adsorbents increased with impregnation concentration of cuprous chloride on activated carbon up to 37wt%, but decreased above impreg-nation concentration of 37%. These adsorbents which show good reappearance of adsorption in recycling experiments could be used for a TSA process.
