(54) Title: CALCIUM HYDROXIDE-CONTAINING COMPOSITIONS AND ASSOCIATED SYSTEMS AND METHODS (57) : 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 treat- ment of exhaust gases and/or removal of contaminants. In some embodiments, the calcium hydroxide-containing compositions can include a D10 from about 0.5 mi- crons to about 4 microns, a D90 less than about 30 microns, and a ratio of D90 to D10 from about 8 to about 20, wherein individual particles include a surface area greater than or equal to about 25 m 2 /g. 104 Milling the Ca(OH) particles to 2 reduce particle size diameter 106 Drying the Ca(OH) 2 particles End FIG. 1 [Continued on next page] 100 Start 102 Combining CaO particles with water to form Ca(OH) 2 particles WO 2018/170255 Al MIDEDIM01101 DIDIREIE301011111111111101111111111111111111111111 Declarations under Rule 4.17: as to applicant's entitlement to apply for and be granted a patent (Rule 4.17(H)) as to the applicant's entitlement to claim the priority of the earlier application (Rule 4.17(iii)) Published: with international search report (Art. 21(3)) before the expiration of the time limit for amending the claims and to be republished in the event of receipt of amendments (Rule 48.2(h))
