Bosch CO2 reduction unit research and development.
1972
Development of Bosch CO2 reduction units for manned spacecraft application has been in progress for a decade. The Bosch process catalytically reacts CO2 with H2 to produce water and carbon. The water may then be electrolyzed to close the biological oxygen and process hydrogen loops. A critical problem has been to confine the reaction so that carbon does not block flow and stop the process. Reaction isolation within a replaceable catalyst cartridge has been successfully demonstrated. Objectives of the current development program are a 25% reduction in operating power, an 80% reduction in expendable weight, and minimized resupply volume.
