Beschreibung
Zusammenfassung:	A process for reducing the concentration of carbon dioxide in a gas including carbon dioxide and water vapour (for example a flue gas or a cement plant flue gas) which process includes contacting the gas with a particulate solid, which solid includes an alkaline earth metal oxide or hydroxide and a promoter selected from an alkanolamine; an unsubstituted or substituted piperazine; an unsubstituted or substituted morpholine; and a polyethyleneamine oligomer.
