활성탄에 대한 CO2-CO-H2 혼합기체의 흡착평형
Adsorption Equilibria of CO2-CO-H2 Mixtures on Activated Carbon
단일성분 CO, CO2, H2 및 혼합기체의 활성탄에 대한 흡착실험을 정적부피흡착법으로 수행하였다. 순수한 성분의 흡착실험결과로부터 구한 등온흡착식의 파라미터들을 사용하여 다성분 흡착평형을 예측하였으며 이성분 및 삼성분 혼합기체에 대한 흡착실험결과와 비교해서 검토하였다.
Coupled Langmuir isotherm, coupled Langmuir-Freundlich isotherm, ideal adsorbed solution theory (IAST), Flory-Huggins vacancy solution theory (FH VST) 중에서 coupled Langmuir
-Freundlich isotherm이 CO, CO2 및 H2의 이성분 및 삼성분 습착을 표현할 때 전반적으로 가장 적절한 것으로 나타났다.
Adsorption experiments for CO, CO2, H2 and their mixtures on activated carbon were performed by static volumetric method. From the parameters obtained from single component adsorption isotherm, multicomponent adsorption equilibria could be predicted and compared with experimental data. Among coupled Langmuir isotherm, coupled Langmuir-Freundlich isotherm, IAST and F-H VST, coupled Langmuir-Freundlich isotherm showed the best agreement with the experimental results for binary and ternary adsorption equilibria of CO, CO2 and H2 on activated carbon.
