Abstract |
The paper discusses results of measuring the rate of reaction of calcined limestone (CaCO3) with sulfur dioxide (SO2) and oxygen (O2) at conditions that eliminate all resistances not associated with the lime (CaO) grain surface. Reactivity increased with the square of the Brunauer, Emmett, and Teller (B.E.T.) surface area when grain size was varied as an experimental parameter. The observed effects of surface area and temperature account for the SO2 capture reported for boiler tests of the limestone injection process. |
