Abstract
Calcium hydroxide-containing compositions can be manufactured by slaking quicklime, and subsequently drying and milling the slaked product. The resulting calcium hydroxide-containing composition can have a size, steepness, pore volume, and/or other features that render the compositions suitable for treatment of exhaust gases and/or removal of contaminants. In some embodiments, the calcium hydroxide-containing compositions can include a Dfrom about 0.5 microns to about 4 microns, a Dless than about 30 microns, and a ratio of Dto Dfrom about 8 to about 20, wherein individual particles include a surface area greater than or equal to about 25 m/g.
