Beschreibung
Zusammenfassung:	To provide a composition for dry flue gas purification that has a good flowability, a good storability, and/or a good absorptivity of pollutants.SOLUTION: The composition contains 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 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.SELECTED DRAWING: None 【課題】良好な流動性、良好な貯蔵性、ならびに／または、汚染物質の良好な吸収率を有する、乾式煙道ガス浄化のための組成物を提供する。【解決手段】１〜９９重量％の炭酸のナトリウム塩の粉末と、１〜９９重量％の吸収性材料の粉末とを含有する。吸収性材料の粉末は０．１ｃｍ３／ｇ以上の比細孔体積を有する。加えて本発明は、乾式煙道ガス浄化のためのプロセスと、炭酸のナトリウム塩の流動性および／または貯蔵性および／またはＨＦ吸収率を改善するための吸収性材料の使用とに関する。【選択図】なし
