Title: ACTIVATION OF A MATERIAL CONTAINING ALKALINE-EARTH CARBONATE AND ALKALINE-EARTH HYDROXIDE FOR THE DRY SCRUBBING OF FLUE GAS
Abstract:
The invention relates to a method for increasing the absorbency of a material containing alkaline-earth carbonate and alkaline-earth hydroxide with regard to sulfur oxides and/or other pollutants, in particular in flue gas, wherein the material containing alkaline-earth carbonate and alkaline-earth hydroxide is activated by heating said material to approximately 250°C to approximately 750°C for a time period of 1 minute to 12 hours.
