| Abstract | In order to improve their CO2 absorption capacity at low temperature, alkali-based sorbents were prepared by impregnation method. It was found that supported CaO modified with a K/Ca molar ratio of 3 kept the most favorable stability and CO2 uptake capacity among the proposed K2CO3-stabilized samples. The result showed that the total CO2 capture capacity of 3K/CaO was 3.84 mg CO2 /g sorbent at 50?C. The X-ray diffraction (XRD) result revealed the new structure was formed during CO2 adsorption such as CaCO3 and K2Ca(CO3 )2. |
