physical chemistry - Why doesn't limestone thermally ...

2021-2-5 · Pure limestone and marble are composed of calcium carbonate: CaCO 3. In air, the temperature required for calcium carbonate decomposition is 898 °C (considering simple equilibrium and ignoring any vapour pressure effects). As pressure increases, the temperature requirement for this equilibrium decomposition increases very rapidly.

An environment-friendly process for limestone

2019-12-10 · CaCO 3 (s) decomposition is the main chemical reaction in limestone calcination, where CO 2 is generated along with the product CaO. Unlike the traditional technology which emits the CO 2 into the atmosphere directly, the LCPCLR system proposed in this paper can recover the CO 2 from the process. Fig. 1 shows the schematic diagram of the LCPCLR. The LCPCLR consists of a shaft

Calcination of Limestone – IspatGuru

The decomposition reaction of the limestone is CaCO3= CaO + CO2 (g). The activation energy of the calcination reaction is generally between 37 kcal/mol to 60 kcal/mol, with values predominantly nearer to 50 kcal/mol. These values are compared with the theoretical value (at equilibrium) being between 39 kcal/mol to 41 kcal/mol. ...

Limestone (CaCO3) is decomposed by heating to

2013-3-1 · Also, one mole of limestone forms one mole of quicklime and one mole of carbon dioxide. So, the amount of quicklime formed equals the amount of carbon dioxide formed and the amount of limestone used. However, you have to convert to moles, not mass. So 1.69 kg = 1690 g, which is 16.88 moles (using molar mass of CaCO3) of limestone (CaCO3).
