Oxygen Regeneration Test Unit for Zero Gravity Operation.

Theoretical and experimental studies have resulted in the development of a carbon dioxide reduction reactor capable of continuous operation at a high rate of reaction. The capability for continuous removal of product carbon has been developed. Satisfactory long duration operation (25 days) of the carbon dioxide reduction unit has been demonstrated. Development of an oxygen regeneration unit which is adaptable to zero gravity operation also required the development of other critical components such as the water condenser-separator and electrolysis unit. Additional catalyst studies should be conducted to reduce the rate of catalyst consumption now obtained through the use of iron catalysts. Unit development and testing should continue until an oxygen regeneration test unit is actually tested in orbit.
