ResumoAbstract Experimental data on sulfation rates of CaO particles derived from CaCO 3 are compared to those derived from Ca(OH) 2 using a product layer diffusion control model differing only in the shape of the CaO grain. Both the model and the experimental data indicate slightly higher reactivity for the Ca(OH) 2 ‐derived oxide due to the observed difference in grain shape. This effect is considered as a contributor to the greater performance of Ca(OH) 2 in pilot‐scale SO 2 removal studies.
