Carbon Dioxide Removal via Passive Thermal Approaches

{ntb_intro_text}A regenerable approach to separate carbon dioxide from other cabin gases by means of cooling until the carbon dioxide forms carbon dioxide ice on the walls of the physical device has been developed. Currently, NASA space vehicles remove carbon dioxide by reaction with lithium hydroxide (LiOH) or by adsorption to an amine, a zeolite, or other sorbent.{/ntb_intro_text}
