| Abstract: | Desulfurization process of a single CaO particle at middle temperature had been calculated using grain model. Some kinetic and physical parameters had been defined by available published data, SEM and TGA. A good agreement between the computational results and TGA data was achieved, which expresses that the model used here can be directly used in the actual theoretical analysis and numerical predict for FGD of CaO at middle temperature. |
