Abstract The report gives results of sulfation behavior measured at 1000 and 1200 C for eight calcium oxide sorbents which were well characterized in terms of particle size, pore structure, and specific surface area. Sulfation results were compared with predictions of a simple mathematical model which applied the measured sorbent characteristics. The comparison, intended to provide direction for model development, suggests need for model improvement in areas such as global kinetics at short times, and accountability for changes in structure due to sintering during sulfation. Subsequently, the effects of the high temperatures on the surface areas of the sorbents in the absence of sulfation were also determined. Surface areas were marginally higher for the larger sorbents at 1000 C injection; but, in general, no correlation between particle size and surface area loss could be found. Surface area decay was shown to be very rapid in the first 200 ms, and subsequently very slow.
