Used clamshells ( Paphia undulata ), as a precursor of calcium oxide (CaO) sorbents, were employed for carbon dioxide (CO 2 ) adsorption in a bubbling fluidized‐bed reactor. To find the optimal calcination conditions, a 2 k experimental design was used to vary the ground clamshell particle size, heating rate, and calcination time at 950 °C under a nitrogen atmosphere. The heating rate was the most significant factor affecting the CO 2 adsorption capacity of the obtained CaO sorbent. The maximum CO 2 adsorption capacity of the CaO obtained under these study conditions was higher than that of commercial CaO.
