CO/sub 2/ separation using facilitated transport ion exchange membranes

Conference · · Sep. Sci. Technol.; (United States)
OSTI ID:5995967
The use of ion-exchange membranes as supports for facilitated transport of CO/sub 2/ is demonstrated. Two different ionomer films were evaluated. The ionomers were a perfluorosulfonic acid film and a sulfonated polybenzimidazole film. Sodium (Na/sup +/) was exchanged into the membrane for diffusion experiments and ethylenediamine (EDA) was exchanged for facilitated transport experiments. The results indicate that thin perfluorosulfonic acid membranes provide the best CO/sub 2/ flux and can also provide exceptionally high selectivity.
