ABSTRACT:
Pressure swing adsorption to remove CO.sub.2 from a gas stream is conducted using an improved alumina obtained by impregnating a starting alumina with a basic solution having a pH of at least 9, e.g. of a basic compound such as KHCO.sub.3, and drying at a temperature low enough to avoid decomposing the basic compound to a form which adsorbs CO.sub.2 such that the compound does not regenerate under reduced pressure purging.
