The effects of particle size, O<SUB>2</SUB> concentration, temperature, and sorbent type on sulfation of calcium sulfide were investigated at temperatures of 650 to 850°C Calcium sulfide particle is oxidized to CaSO<SUB>4</SUB> through reaction: CaS + 2O<SUB>2</SUB>↑CaSO<SUB>4</SUB> when reaction temperature is below 850°C. CaS particle with a diameter below 0.005 mm was found to achieve complete conversion to CaSO4. However, CaS particle with a diameter above 0.02 mm wasn't be completely converted to CaSO4 due to the pore blockage of sulfate product layer. A kinetic study of the sulfation reaction (CaS + 2O<SUB>2</SUB> ↑CaSO<SUB>4</SUB>) has shown its activation energy to be 57.2 kJ/mol. A grain model has been developed to analyze the oxidation reaction within a CaS particle. The effects of temperature, O<SUB>2</SUB> concentration, particle size and type of limestone on the reaction process were discussed.
