- <p>This study investigated the reaction kinetics of calcium hydroxide (Ca(OH)<sub>2</sub>) with carbon dioxide (CO<sub>2</sub>) at 180°C, near the maximum operating temperature range of bag-filter systems. Experiments revealed that Ca(OH)<sub>2</sub> reacts with CO<sub>2</sub> to form predominantly crystalline calcium carbonate (CaCO<sub>3</sub>). Higher CO<sub>2</sub> and H<sub>2</sub>O concentrations enhanced the conversion. Kinetic analysis using the unreacted core model indicated that the rate-controlling step shifted from surface reaction control to diffusion control in the product layer. Higher H<sub>2</sub>O concentrations increased the effective diffusion coefficient and delayed this transition. This shift is attributed to surface coverage and plugging of fine pores of Ca(OH)<sub>2</sub> by the formation of a CaCO<sub>3</sub> layer, which increases diffusion resistance in the product layer. H<sub>2</sub>O concentration may also affect the pore structure of the formed CaCO<sub>3</sub>. These findings suggest that Ca(OH)<sub>2</sub> in flue gas treatment systems can be potentially utilized for simultaneous CO<sub>2</sub> capture at high temperatures.</p>
