The fixed-bed operation was employed to examine the carbon dioxide capture ability. Repetitive calcination/carbonation reaction with the hydration treatment was also operated to enhance the reactivity and durability of the sorbents for carbon dioxide capture. Conversions for the repetitive calcination/carbonation reaction of modified limestone were evaluated under different operating conditions. The empirical model for the decay of the carbon dioxide capture capacity from the previous investigation was presented in comparison with the experimental results.
