Abstract
The rate of reaction of calcined limestone with SO2 and O2 was measured at conditions that eliminate all resistances not associated with the CaO grain surface. Reactivity increased with the square of the BET 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.Keywords
