Oxygen recovery by the catalytic dissociation of carbon dioxide.

I N A PREVIOUS paper/ the problems concerned with oxygen recovery systems for manned space flight were examined. A procedure was described which led to the purification of the atmosphere and at the same time, permitred the two major atmospheric contaminents, CO s artd H20, to be collected for further use as warranted. It was suggested that the oxygen content of the entrapped water become available by the process of electrolysis. The remainder of the paper concerned itself with methods for the recovery of O 2 from CO2. Although many techniques were mentioned, six were described in detail. These six include:
