Beschreibung
Zusammenfassung:	The invention relates to a composition for the purification of flue gas containing 1 to 99 wt. % of a powder of a sodium salt of carbonic acid and 1 to 99 wt. % of a powder of an absorptive material, wherein the powder of an absorptive material has a specific pore volume that is equal to or greater than 0.1 cm3/g. The invention also relates to a process for dry flue gas purification and the use of an absorptive material to improve the flowability and/or storability and/or HF absorptivity of a sodium salt of carbonic acid.
