Abstract

Used clamshells (Paphia undulata), as a precursor of calcium oxide (CaO) sorbents, were employed for carbon dioxide (CO2) adsorption in a bubbling fluidized-bed reactor. To find the optimal calcination conditions, a 2k 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 CO2 adsorption capacity of the obtained CaO sorbent. The maximum CO2 adsorption capacity of the CaO obtained under these study conditions was higher than that of commercial CaO.
