PULVERULENT LIME COMPOSITION, METHOD FOR THE PRODUCTION THEREOF, AND USE OF THE SAME

摘要

Powdered lime composition having a BET specific surface area that is equal to or greater than 25 m2/g and a BJH total pore volume obtained from nitrogen desorption that is equal to or greater than 0.1 cm3/g, and furthermore comprising an alkali metal. The alkali metal content is equal to or greater than 0.2% and equal to or less than 3.5% based on the total weight of the composition. There is also described a method of preparing the composition and use thereof to reduce flue gases.
