Abstract

고정층 반응기에서 cesium carbonate 흡착제를 사용하여 이산화탄소(CO2), 질소 및 수분의 혼합기체로부터 CO2를 수착하여 CO2-cesium carbonate의 반응속도론을 구하기 위하여 CO2의 파과곡선을 측정하였다. 비촉매 불균일반응계에서 반응속도론을 해석하기 위하여 CO2의 파과곡선을 사용하여 비활성화 모델로부터 반응속도론을 구하고 CO2의 파과곡선의 비선형해석으로부터 비활성화 모델에서 수착속도상수와 비활성속도상수를 구하였다.
Cesium carbonate was used as an adsorbent to capture carbon dioxide from gaseous stream of carbon dioxide, nitrogen, and moisture in a fixed-bed to obtain the breakthrough data of CO2. The deactivation model in the non-catalytic heterogeneous reaction systems is used to analyze the sorption kinetics among carbon dioxide, carbonate, and moisture using the experimental breakthrough data. The experimental breakthrough data are fitted very well to the deactivation_x000D_ model than the adsorption isotherm models in the literature.
