The sulfation behavior of calcined raw meal was investigated in a laboratory fix-bed reactor under conditions typically for SO2 capture in the kiln inlet housing used in cement production. The initial period is characterized with a fast-increasing conversion, while the second period shows a slow-increasing conversion. A desirable temperature exists for sulfation of calcined raw meal. A smaller particle size favors the sulfation reaction. The initial conversion rate is significantly promoted by a higher SO2 concentration. The SEM examinations show that the sulfation process involves nucleation and growth of CaSO4 grains- the sulfation product. Increasing the temperature and extending the time result in fewer but larger CaSO4 grains in the product layer.
