Abstract

Removing CO₂ and conserving water efficiently in a spacecraft are crucial. Dehumidifying methods are necessary. This study examined the effects of heating temperature, air flow rate, humidity, and desorption time on absorption time. The ability of Zeolite and CSX-250 to absorb and desorb moisture was clarified by experiment. The experiments showed the potential of CSX-250 to maintain the dew point temperature needed for effective CO2 removal.
