WebJan 1, 2011 · This process is based on the reversible gas-solid reaction between CaO and CO 2 to form calcium carbonate (CaCO 3 ) (Equation 1). The forward reaction (carbonation) can be used to remove CO 2 from a mixture of gases, and when heat is applied to the CaCO 3 the CO 2 can be released via the reverse reaction (calcination), and the CaO regenerated.
