A Regenerative Carbon Dioxide Removal System for the AAP Cluster 690626

A regenerative carbon dioxide removal system being developed for spacecraft life support systems comprises two molecular sieve canisters. The canisters operate in cycles and maintain the carbon dioxide percentage within required levels for a three-man crew over a minimum period of 28 days before regeneration is required. Unlike the expendable chemical removal techniques used for Gemini and Apollo, the cyclic, nonexpendable adsorption system can meet, with a minimum weight penalty, the carbon dioxide removal requirements of extended space flights planned in the future.
