The Kinetic Model of Calcination and Carbonation of Anadara Granosa

Utilization of calcium-based adsorbent in carbon dioxide (CO2) separation from the gas stream through the calcination and carbonation process is extensively applied in the gas purification process, especially at the elevated reaction temperature. Typically, natural calcium carbonates (CaCO3) such as...
