  • Calcium Carbonate Decomposition | Springerlink

    Abstract. Calcium carbonate decomposes under well-defined conditions giving CaO (solid) and CO 2 (gas). The process kinetics are known to be strongly influenced by the CO 2 partial pressure and temperature. In dynamic conditions, as in thermogravimetric analysis (TG) and differential thermal analysis (DTA), kinetics influence the observed heat effect and mass losses, as was shown in semi.

  • Catalytic Activity Of Lime For N2O Decomposition

    2016-2-24 · To understand the contribution of lime to the abatement of N2O emission from fluidized coal combustor, the catalytic activity of the lime for the decomposition of N2O under coal combustion conditions was studied. Lime was active for the catalytic decomposition of N2O, and its activity was stable in the simulated coal combustion flue gas in the absence of SO2 at 800 °C.
