농도-펄스법에 의한 기체 삼성분계 흡착 등온식의 산출
Determination of Adsorption Isotherms of Gaseous Ternary System by Concentration-pulse Technique
김부웅, 구헌서
선형흡착평형상수(k1)를 포함한 삼성분계(흡착기능 물질 2 + 운반기체 1)의 흡착 모델 식을 C1/C1=k1+α1 C1m1 + β12 C2n12와 같이 설정하고, 이성분계(흡착기능 물질 1 + 운반기체 1)에 대하여 크로마토그래피-perturbation방법 중 농도-펄스기법(concentration-pulse technique)과 모멘트 분석에 의한-에 의하여 설정된 삼성분계 모델식의 변수값을 산출하였으며 이를 크로마토그래픽에 의한 삼성분계 실험으로 확인하므로써 정적인 방법(static method)에 의하여 검증하던 종전의 과정을 크로마토그래피 자체만으로 수행할 수 있었다. 그 결과 설정된 모델식으로 계의 해석이 가능하였고 농도-펄스기법의 적용을 흡착 가능한 물질 2종과 흡착평형상수로부터 benzene, n-octane, chloroform의 흡착열(Had)을 van’t Hoff식에 의하여 -10.07, -8.66, -6.26kcal/gmol로 각각 구하였다.
The model of adsorption isotherm for ternary system contained 1 non-adsorbable and 2 adsorbable species was set up as C1/C1=k1+α1C1m1+β12C2n12. The parameters in model equation were produced from adsorption experi-ments of binary system(adsorbable species 1+non-adsorbale species 1) by concentration-pulse technique of perturba-tion method, and moment analysis. The isotherm equations of ternary systems were verified by ternary system experi-ments with only gas chromatography itself, without static method. Therefore it is possible the application of concentra-tion-pulse technique to extend to the ternary gas system contained 1 non-adsorbable and 2 adsorbable species. And the adsorption heats(Had) of benzene, n-octane, and chloroform was calculated by van’t Hoff equation with adsorption equilibrium coefficients by moment analysis as -10.07, -8.66, -6.26kcal/gmol respectively.
