Researchers at NASA’s Marshall Space Flight Center are refining a system-level model of the Carbon Dioxide Removal Assembly (CDRA) which will aid in the design of the next generation four-bed molecular sieve for human exploration beyond low earth orbit. A vacuum characterization test-stand (VCTS) has been built to study sorbent thermal and sorption characteristics in support of this modeling effort. This paper describes the VCTS and presents experimental results of hydraulic and thermal characterization, CO2 breakthrough, and vacuum desorption tests on the VCTS. We then compare experimental results with the one-dimensional model.
