Abstract: A process and apparatus for the removal of carbon dioxide from a gaseous stream, wherein the CO2 content ranges from trace amounts up to 50 mole percent, and for subsequent transfer to another gas stream by thermal regeneration. A special composition comprising a finely ground mixture of potassium carbonate and alumina, which has synergistic properties, is used as the absorbent. In a preferred apparatus embodiment, the mixture is incorporated into a rotary regenerative wheel.
