The objective of the program was the development of an immobilized liquid membrane for CO2 removal from a manned spacecraft. During basic film research, water was found to be better than a polymeric material or any pure liquid for CO2O2 separation. An immobilized film of water was available in the form of a porous cellulose acetate membrane. By impregnating this membrane with a concentrated solution of CsHCO3Cs2CO3, and a catalyst for the hydrolysis of CO2, CO2 transport was facilitated and O2 transport was decreased to obtain a CO2O2 separation factor and CO2 permeability of 4100 and 55, 796 x 10 to the -9th power. A mathematical analysis of CO2 transport was also carried out. It will now be possible to build a single-stage CO2 removal system with minimum power, weight, and size requirements. Author
