Abstract:

A laboratory-scale experimental program was con ducted which clearly indicated the feasibility of operating a continuous flow electrochemical device to remove carbon dioxide from the atmos phere and to generate oxygen. Carbon dioxide was removed by a combination of absorption and elec trodialysis, while oxygen was generated at anodes by the electrolysis of water. Any ratio of car bon dioxide removal to oxygen generation was possible since satisfactory operation was obtained from electrolytic stacks which 1 absorbed carbon dioxide with minimum oxygen generation, 2 absorbed carbon dioxide and generated oxygen in approximately a 21 mole ratio, and 3 generated oxygen with no absorption of carbon dioxide. One of the most important design parameters was found to be the applied current density. Equipment weight decreased but power requirements increased with increased current densities. A three-man unit was designed which was weight optimized for power penalties of 100 and 300 lbkw. The unit was designed to remove 6.75 lbsday of carbon dioxide and to generate 6.00 lb ay of oxygen. To handle these capacities, the weight-optimized unit weighed 61 lbs, had a volume of 1.5 cu ft and a power requirement of about 1,600 watts. Author
