Abstract
The paper discusses the calcination and sintering of sorbents during boiler injection for dry sulfur dioxide (SO2) control, with emphasis on calcium hydroxide--Ca(OH)2--because of its superior reactivity with SO2 and its wide commercial availability. Calcination and sintering are of particular interest because they produce the surface area, pore volume, and pore size distribution which are responsible for reactivity of the sorbent with SO2. Particle size is also a significant factor. Considerable EPA work has been directed toward increasing the calcium utilization of Ca(OH)2 during furnace injection. Hydroxides have been produced using a variety of surfactants in the water of hydration in an attempt to reduce particle size by preventing agglomeration. Calcium lignosulfonate was shown to be the most cost effective material for reducing particle size in laboratory-scale hydrations.
