Abstract

A porous material for absorbing carbonic acid from air and liberating oxygen consists of an alkali peroxide mixed with a material containing water of crystallization in such quantity as to give half a molecule of water for each molecule of peroxide. On locally heating the mixture a reaction occurs resulting in the conversion of some of the peroxide into a low hydrate, probably of the form Na2O22H2O. Suitable substances for admixture with the peroxide are sodium sulphate or carbonate crystals, or sodium peroxide hydrate Na2O28H2O. A catalyst may be added before or after the production of the porous material. Suitable catalysts are the oxides or hydrates of copper, manganese, nickel, cobalt, silver, cerium, uranium, tungsten, molybdenum, vanadium, chromium, thallium the alkalies, alkaline earths and rare earths or a metal powder.
