Abstract

본 논문에서는 액상흡착평형을 열역학적으로 해석하여 흡착상에서의 몰분율과 활동 도계수간의 관계를 고찰하고자 하였다. 30 ℃에서 Zeolite Na Y 및 Na X에 대한 벤젠-사이클로헥산계, 톨루엔-사이클로헥산계의 흡착평형데이터를 실험을 통하여 얻었으며, 흡착평형데이터로부터 계산한 흡착상의 활동도계수는 열역학적으로 건전하였다. 또한 흡착평형데이터를 이용하여 선택흡착되는 성분의 순성분흡착량도 얻을 수 있었다.

The relations between the mole fraction and the activity coefficient in the adsorbed phase were obtained from the thermodynamic analysis on the adsorption equilibrium of liquid mixtures. the asorption equilibroium data of the liquid mixtures, benzene-cyclohexane and tolune-cyclohexane, on the zeolite Na y and Na X were measured at 30 ℃. the activity coefficients in the adsorbed phase, calculated from the adsorption equilibrium data, were thermodynamically consistent. It was found that the amout of preferentially adsorbed molecules could be calculated from the experimental adsorption equilibrium data.
