US5492685A - High surface area hydrated lime and method of .Thus, it is desirable to provide calcium hydroxide having high surface area, high porosity, and small particle size for use in SO 2 sorption, and for other physical processes relying on the sorptive capabilities of calcium hydroxide. In the past, conventional hydrates of calcium produced by slaking lime (CaO) produced by.producing high surface hydrated lime,producing high surface hydrated lime,HIGH-SURFACE-AREA HYDRATED LIME FOR SO2 CONTROL.INTROWCTION. For many site specific applications, dry sorbent injection technologies offer advantages over the wet flue gas desulfurization systems for controlling the emissions of SO produced during combustion of high sulfur coal. These potential advantages incluse ease of retrofit, dry waste, and lower capital.

Preparation of Calcium Silicate Reagent from Fly Ash and Lime in a .

The batch reaction between fly ash and hydrated lime in water to produce high surface area calcium silicates for flue gas desulfurization has been examined extensively. This paper examines the reaction in a flow reactor using two low-calcium fly ashes and introducing gypsum, calcium sulf ite hemihydrate, and calcium.

Preparation of calcium silicate absorbent from iron blast furnace slag.

The SO2 reactivity of solids prepared with gypsum greatly exceeded that of hydrated lime, achieving greater than 70-80% conversion of the alkalinity after 1 hr of reaction with SO2. The use of CaCl2 as an additive to the lime/slag system, in lieu of gypsum, also produced high-surface-area solids, 115 m2/g after 21 hr of.

Calcium hydroxide - Wikipedia

At ambient temperature, calcium hydroxide (portlandite) dissolves in pure water to produce an alkaline solution with a pH of about 12.4. Calcium hydroxide solutions can cause chemical burns. At high pH value (see common ion effect), its solubility drastically decreases. This behavior is relevant to cement pastes. Aqueous.
