Study of Limestone Calcination with CO2 Capture .

Study of Limestone Calcination with CO2 Capture .

In the present work, the effects of temperature (up to 1293 K) and residence time on the decomposition behaviors of limestone particles (0.25−0.5 mm) in a CO 2 atmosphere were investigated using a continuously operating fluidized bed reactor for CO 2 capture. The results show that the rate of limestone decomposition was strongly dependent upon the pressure difference between the equilibrium .

Calcination - Wikipedia

Calcination - Wikipedia

In limestone calcination, a decomposition process, the chemical reaction is CaCO 3 → CaO + CO 2 (g). The standard Gibbs free energy of reaction is approximated as ΔG° r = 177,100 − 158 T (J/mol). The standard free energy of reaction is 0 in this case when the temperature, T, is equal to 1121 K, or 848 °C. Oxidation. In some cases, calcination of a metal results in oxidation of the metal.
