The sulfation properties of six different natural limestone and hydrated lime slurries were investigated. Sulfation experiments were carried out at the temperatures of 323 K and 298 K in a gaseous mixture consisting of 5% O2, 10% CO2, 0.5% SO2 and a balance of nitrogen by volume. Total sulfation capacities of the slurries were found to …
