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. Accomplishments during the first year include: (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. Project Year No. 2 research work included: (1) a continuation of the collection and characterization of a set of Ohio limestones, (2) the production of a complete set of calcined and hydrated products from the set of Ohio limestones, and (3) an investigation of the importance of lime solubility enhancement in the evolution of surface area during the slaking process.
