Zeolite 5A에서의 H2/CO/CO2 단성분 및 혼합성분의 흡착평형
Pure Gas Adsorption Equilibrium for H2/CO/CO2 and Their Binary Mixture on Zeolite 5A
안의섭, 장성철, 최도영, 김성현, 최대기
Zeolite 5A 촉매에서 H2, CO, CO2에 대한 단성분 및 혼합성분의 흡착평형 실험을 정적부피법에 의해 수행하였다. 실험 데이타는 온도범위 293.15 K, 303.15 K, 313.15 K이고, 압력범위는 25 atm까지로 하여 얻었다. 각각의 파라미터 들은 단성분 실험을 통해 얻었고, 이를 통해 혼합성분의 흡착 평형을 예측하였으며 실험값과 비교하였다. Zeolite 5A 에서의 H2/CO2, CO/CO2 혼합가스의 흡착평형 실험 결과는 Langmuir isotherm, Langmuir-Freundlich isotherm and Dual-Site Langmuir isotherm을 이용해 예측하였다. 그 결과 Dual-Site Langmuir isotherm모델이 가장 유사한 예측을 하는 것으로 나타났다.
Adsorption experiments for H2, CO2, CO, and their binary mixtures on zeolite 5A were performed by static volumetric method. Experimental data were obtained at temperatures of 293.15, 303.15 and 313.15 K and at pressures to 25 atm. The parameters obtained from single component adsorption isotherm. Multicomponent adsorption equilibria could be predicted and compared with experimental data. Langmuir isotherm, Langmuir-Freundlich isotherm and Dual-Site Langmuir isotherm be used to predict the experimental results for binary adsorption equilibria of CO2/CO and H2/CO2 on zeolite 5A. Dual-Site Langmuir isotherm showed the best agreement with the experimental results.
