Calcination - WikipediaDeze pagina vertalen

    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.

    Calculating CO2 Emissions from the Production of Lime ...

    which limestone, which is mostly calcium carbonate (CaCO 3) is heated in a kiln to produce quick lime (CaO). Carbon dioxide is a byproduct of this reaction and is usually emitted to the atmosphere. However, some facilities recover a portion of the emissions- e.g. for use in sugar refining and precipitated calcium carbonate production.
