ABSTRACT:
This invention relates to a CO.sub.2 /H.sub.2 O sorbent comprised of silver oxide, a CO.sub.2 sorption promoter, and a support. Preparation of this sorbent consists of impregnating the support with a silver compound, converting the silver compound to silver carbonate or silver oxide, and further impregnating the support with a CO.sub.2 sorption promoter. Prior to use as a sorbent, the silver carbonate is converted to silver oxide via the application of heat; liberating CO.sub.2 and H.sub.2 O.
