Description:
The paper gives results of a characterization of post-furnace injection solids and flyash mixtures and their testing in a bench-scale reactor for the removal of SO2. Virtually no SO2 removal was observed with untreated solids. High SO2 capture occurred when the samples were hydrated and dried prior to SO2 exposure. The SO2 capture by solids increased with increasing time and temperature of hydration. For the same time/temperature conditions of hydration, higher SO2 capture was achieved with solids of higher flyash/sorbent ratio. A possible mechanism of enhanced SO2 capture by hydration of the product solids is discussed. (Copyright (c) 1987, The American Chemical Society.)
