Two-Bed Carbon Molecular Sieve Carbon Dioxide Removal System Feasibility Testing

The regenerate two-bed carbon dioxide removal system, utilizing carbon molecular sieve (CMS), represents a significant advancement over the current Space Station four-bed zeolite molecular sieve baseline system. To demonstrate the feasibility of the CMS system approach. AiResearch conducted system performance tests on a two-bed system created by modifying the existing flight qualified Skylab regenerable carbon dioxide removal system. Results of the performance tests confirmed the two-bed CMS system approach as a viable candidate for Space Station regenerable carbon dioxide removal.
