Abstract
In a closed space system at a ground test facility with environmental control and life support system, carbon dioxide as the products of human and animals respiration is adsorbed and condensed by solid amine and desorbed by aqueous vapor (steam).
The carbon dioxide is then reduced to methane and water using hydrogen. Oxygen is recovered from the produced water using an electrolytic system with a solid polymeric membrane and will be reused for respiration.
This report describes the result of the fundamental research on individual technological elements: the reduction of carbon dioxide using hydrogen, the decomposition of produced methane and the water electrolysis.
