| abstract |
The present invention relates to a hydrated-lime-based composition, to a method for producing such a composition and to the use thereof for treating fumes or flue gases (by means of a dry or substantially dry treatment process), in particular to reduce the chlorine, sulphur and halogen compounds in exhaust gases or flue gases, especially acid flue gases. Said composition comprise a high surface area hydrated lime, a first additive selected from NaCl, Na 2 SO 4 and CaCl 2 , a sodium compound selected from NaOH, Na 2 CO 3 and NaI— and less than 5% by weight water. |
