Summary:

TDA Research, Incorporated (TDA) is developing a simple system that provides an effective way of interfacing the carbondioxide (CO2) removal and reduction functions. The system uses a chemical absorbent and a Sabatier catalyst combination to remove the CO2 and water vapor (H2O) produced by metabolic processes from cabin air and subsequently reduce the CO2 to methane and water. The system has the potential to weigh less than the Four Bed Molecular Sieve and CO2 Reduction Assembly combination, which is connected with a CO2 pump/compressor and storage tank due to the high CO2 absorption capacity of the sorbent and its ability to simultaneously absorb both CO2 and H2O (which eliminates the need for desiccant beds in the Four Bed Molecular Sieve System). The system does not require a CO2 pump/compressor or storage tank offering energy savings that come from effective utilization of the heat released by the Sabatier reaction to drive sorbent regeneration. Previously, TDA developed a high capacity regenerable CO2 and H2O sorbent to support the operation of the system and showed that the sorbent maintains its activity over extended cycling (Alptekin and others, 2003). We also demonstrated the operation of a state-of-the-art catalyst under the operation conditions of interest (Alptekin and others, 2003). Recently, TDA built a prototype of the system to demonstrate the key aspects of the process. This paper briefly describes the prototype system and summarizes the results of the demonstration tests
