The report gives results of a study to develop an understanding of the factors that control the reactivity of hydrated sorbents toward SO2 in coal fired furnaces. It focused on the impacts of hydrate properties (e.g., particle size, surface area, and chemical composition) and the furnace temperature of the injection location. A bench scale hydrator was used to produce atmospheric and pressure hydrated sorbents, with parameters pertinent to the hydration process varied. Study results indicate that pressure hydrates generated under well controlled conditions are more reactive than commercially produced atmospheric hydrates. The important production and operating parameters for the pressure hydration process included the size and composition of the quick-lime, the hydration temperature and pressure, the rate of water addition, and the pressure progression during discharge. All hydrates, atmospheric and pressure, exhibited a strong dependence on injection temperature.
