Sorbent preparation techniques used today have generally been adapted from techniques traditionally used by the lime industry. Traditional ``dry`` hydration and slaking processes have been optimized to produce materials intended for used in the building industry. An experimental program is being carried out for the purpose of (1) defining the effects of slaking conditions on the properties of calcium-based sorbents, (2) determining how the parent limestone properties and preparation techniques interact to define the SO{sub 2} capture properties of calcium-based sorbents, and (3) elucidating the mechanism(s) relating to the activity of various dry sorbent additives. Work has focussed in the areas of experimental set-up (all experimental apparatus has been built from the ground up) and the learning/selection of analytical techniques for sorbent characterization. Accomplishments (1) the collection of a series of limestone/ hydrated lime/ quicklime samples representing a range of Ohio limestone products, (2) initial analyses of the suite of Ohio limestones, (3) the set-up/shakedown of a mercury porosimeter, (4) the design and construction of a bench-scale slaking reactor, and (5) the design and construction of a bench-scale calcination reactor. Effects of various additives is discussed.
