The KMgAl Sorbents for CO₂ Capture from Coal-Fired Power Plant

Abstract:

The KMgAl sorbents for CO₂ capture was investigated in this study. The sorbent showed a maximum CO₂ capture capacity with MgO loading of 10 wt % at low temperature in simulated flue gas. The presence of an appropriate amount of water vapor pretreatment had a positive effect on the CO₂ capture capacity. Furthermore, the XRD results revealed that the main active species K₄H₂(CO₃)₃•1.5H₂O appeared after water vapor pretreatment with 0-20 min and Mg₄Al₂(OH)₁₂CO₃•3H₂O formed as the time of water vapor pretreatment increased. The main products KHCO₃ and K₂Mg(CO₃)2•4H2O formed over the sorbent pretreated with water vapor after CO₂ adsorption in the absence of water vapor.
