EPA's efforts to develop low cost, retrofit flue gas cleaning technology include the development of highly reactive sorbents. Recent work addressing lime enhancement by slurrying with siliceous materials and testing in a laboratory packed-bed reactor is discussed in the report. The solids generated from a furnace limestone injection process were reactivated by slurrying at elevated temperatures. Compared with untreated solids, reactivity toward SO2 was significantly enhanced by hydration. The SO2 capture by solids increased with increasing time and temperature of hydration. The SO2 capture was probably enhanced by the calcium aluminate silicate hydrates formed during the slurrying process.
