Abstract

A sorbent composition with improved acid gas reactivity comprising calcium hydroxide particles is provided. In the calcium hydroxide composition, the amount of time it takes the calcium hydroxide particles to neutralize in citric acid of a mass greater than 10 times the mass of the calcium hydroxide particles is less than 10 seconds; about 90% of the calcium hydroxide particles are less than or equal to about 10 microns; and the calcium hydroxide particles have a BET surface area of about 18 m/g or greater.
