Al2O3 흡착제를 이용한 객실용 이산화탄소 흡착연구

초록

Carbon dioxide concentration of railroad passenger cabin is obliged to be kept lower than guideline values of 'Indoor air quality guideline for public transportations', but actual carbon dioxide concentration frequently exceeds this guideline value during the morning and evening rush hours. For improving comfortability and satisfaction of passengers, concentration control method using Al2O3 adsorbents was presented. The adsorbent is made from Al2O3 and LiOH. Al2O3 perform as a frame and LiOH as a chemical adsorbent. The adsorbent performance experiment was carried out by measuring concentration change of Carbon dioxide in terms of flow, initial concentration and amount of adsorbent. It is expexted that the obtained results will be used to lower carbon dioxide concentration of railroad passenger cabin.
