Supported amines have been identified as potential regenerable sorbents that maximize capture of CO2 andwater vapor while minimizing regeneration power requirements for long duration human space flightapplications. In this study, the parameters governing the efficiency of the sorption and regeneration processunder temperature swing absorption conditions were investigated. Desorption pressure (9-93 mmHg) anddesorption temperature (30-60 
C) were identified as the most significant factors affecting capture in thesupported amine system. Increasing the temperature of the desorption step permitted utilization of a weakervacuum for removal of moisture and CO2, and thus reduced the energy requirements for desorption. Apreliminary thermal energy analysis shows this system to use less than 25% of the energy required forregeneration of the zeolite sorbent system operated on the International Space Station.
