객실용 이산화탄소 흡착제 적용방안 연구

초록

Passenger cabin is crowded with many passengers during rush-hour, and CO₂ is generated by the breathing of passengers. Recently, the concentration of CO₂ and particulate matters is forced to be controlled to lower than certain level according to the Government guideline. In general, particulate matters are easy to control, but CO₂ is hard to do due to the difficulties in ventilation. Especially for the train running through tunnels, the ventilation to decrease CO₂ concentration may worse the indoor air quality of the cabin. In this study, CO₂ adsorbent was prepared, and its adsorption performance was tested with a small reactor. The mixing ratio of the adsorbent was varied, and the optimal mixing ratio was investigated in this study.
