A current of hot air, with a CO 2 partial pressure of 40 Pa, can remove carbon dioxide at 536°C, but kiln gases contain perhaps 35% CO 2, and would decompose pure calcite only above 829°C. In reality, in a kiln burning a normal cement rawmix, decomposition begins at around 650°C. This, put simply, is because the clay components (or their ...
