Abstract—The limestone calcination reaction is endothermic (CaCO3>CaO CO2 H 1660 kJ /kg) whichThis generates CO2 in the process leading to inhibition of calcination reaction. Microwave heating of limestone is proposed to increase the temperature of the limestone to the desired levels. CaCO3 CaO CO2 1 1 :1. First we write the mole ratio of the reactant and the products.CaCO3 Heat Energy CaO CO2. Endothermic reactions break the bonds whereas Exothermic reaction form bonds. Heats of Formation, or Enthalpies of Formation, are used to provide a concise collection of thermochemical data. Use Hof for CaCO3, CaO and CO2 to determine the standard heat of reaction for. CaCO3(s) CaO(s) CO2(g). The forward reaction is endothermic, 178kJ of heat energy is absorbed (taken in) for every mole of calcium oxide formed.From rule 1: increasing the temperature will increase the yield of calcium oxide or lime, CaO which is endothermically formed. Emissions: Use of solar energy for process heat eliminates CO2 emissions produced during the energy-intensive capture process.Carbonation step: ambient air and steam is the fluidizing gas, CaO is transformed to CaCO3,and CO2-depleted air leaves the reaction site. 2NH3(g) CO2(g). The KP 2.
