| Abstract |
For reduction of CO2 emission to atmosphere, many kinds of mid- and high-temperature CO2 absorbents have been researched and developed. But, most researches on mid- and high-temperatures CO2 absorbents were usually based on main group elements such as MgO, Mg–based absorbents, Ca–based absorbents and Li–based absorbents.
However, in this paper, we focus on transition metal based material, CdO, as a mid temperature CO2 absorbent. CdO itself doesn’t show any CO2 absorption, so we put NaNO3 into CdO system for promoting CO2 absorption and desorption. Up to 78% of CdO conversion efficiency was achieved, although the absorption ability decreased as the absorbent was used repeatedly in cycle, due to the growth of particles in size.
For investigation on the growth of particle size, several analyses were conducted. Herein, we found that dissolution of CdO and CdCO3 in molten NaNO3 is necessary in respect of facilitating CO2 absorption and desorption.
