Use of base treated alumina in pressure swing adsorption

Pressure swing adsorption to remove CO2 from a gas stream is conducted using an improved alumina obtained by impregnating a starting alumina with a basic compound solution having a pH of at least 9, and drying at a temperature low enough to avoid decomposing the basic compound to a form which adsorb...

Summary:Pressure swing adsorption to remove CO2 from a gas stream is conducted using an improved alumina obtained by impregnating a starting alumina with a basic compound solution having a pH of at least 9, and drying at a temperature low enough to avoid decomposing the basic compound to a form which adsorbs CO2 such that the compound does not regenerate under reduced pressure purging.
