Preparation and Characterization of Desulfurization Sorbent from Hydrated Lime and Blast Furnace Slag
A series of sorbents for SO2 in flue gas were prepared from hydrated lime and blast furnace slag using a factorial experiment design. It is found that the reaction between hydrated lime and blast furnace slag is fast. The reactivities of the as-prepared sorbents are higher than those of hydrated lime alone due to the formation of calcium silicate hydrates, and hence the utilization of hydrated lime as well as the Ca in the blast furnace slag is improved. Furthermore, the effects of preparation variables on the reactivity of the sorbents are also discussed.
