NaY Zeolite에 대한 Benzene-Cyclohexane 혼합물의 흡착열
Heat of Adsorption for Benzene-Cyclohexane Mixtures on NaY Zeolite
지올라이트 NaY에 대한 벤젠-사이클로헥산 액체혼합물의 흡착열을 새로이 제작한 열량계를 이용하여 20, 25, 30 및 35 ℃에서 측정하였다. 벤젠의 픕착열은 사이클로헥산보다 크고 온도의 영향을 더 많이 받았다.
벤젠이 지올라이트 NaY에 선택흡착되었으며, 측정한 흡착열과 기지의 물리적 데이터로부터 흡착량을 추정할 수 있었다. 또한 액상에서 벤젠의 물분율이 0.3이상이 되면 흡착은 더 이상 일어나지 않았다.
The heat of adsorption which was measured by the modified calorimeter was experimentally obtained from the system of benzene-cyclohexane-NaY zeolite at 20, 25, 30 and 35 ℃, respectively. The heat of adsorption of benzene was greater than that of cyclohexane, and was more sensitive to temperature.
Benzene was preferentially adsorbed on NaY zeolite, and the amount of adsorption was calculated from the heat of adsorption and the experimentally measurable properties. The amount of adsorption was rarely increased as the mole fraction of benzene over 0.3 in the liquid phase.
