An unreacted shrinking core model with variable effective diffusivity is applied to sulphation test data from a pressurized thermogravimetric apparatus for various limestone and dolomite samples. The test are conducted under typical conditions for a pressurized fluidized bed combustor. At these conditions the limestone remains uncalcined, while the dolomite is halfcalcined. The solsorbents are characterized by chemical composition analysis, particle density measurements, mercury porosimetry and bet internal surface measurement.
