Lime is produced in lime kilns, where limestone is heated until the limestone is converted to lime and carbon dioxide (CO 2). This thermal treatment of limestone is called calcination, and can be described as CaCO 3 → CaO + CO 2. Calcination is a highly endothermic reaction, causing the energy requirement to be high for the process.
Partially calcined limestone (PCL) was produced via calcination of limestone powders at temperatures below 900 °C. The calcination process is outlined in Fig. 3. Limestone gradually decomposed from its outer surface to the interior in practical production, releasing CO 2 and forming pore pathways. Even after complete decomposition, the ...
