High capacity adsorbent for oxygen storage at cryogenic temperature
An oxygen storage adsorbent at cryogenic temperatures that will remove carbon dioxide and water comprises a carbonized precursor material having functional sites that adsorb and store oxygen and that evolve oxygen upon adsorbing carbon dioxide and water. The adsorbent is characterized by a total pore volume of between about 0.5 to 0.6 cm3/g, a median pore diameter between about 0.42 to 0.46 nm, and a BET surface area between about 1000 to 1200 m2/g.
