MIXED-GAS ADSORPTION AND VACUUM DESORPTION OF CARBON DIOXIDE ON MOLECULAR SIEVE - BED PERFORMANCE AND DATA ANALYSIS

A molecular sieve CO2-removal system was built, based on a rigorous mathematical analysis and predesigned experimental program. The system was constructed for a specific task””to maintain an Apollo Spacecraft cabin at a CO2 partial pressure below 7.6 mm. of Hg for at least 45 days with a CO2-removal rate equal to the production rate of three men. A closed chamber test was conducted for 48 days, during which time the system performed according to specification. Analytical techniques developed in connection with the system development accurately described system performance under normal and accelerated operating conditions. © 1969, American Chemical Society.
