ABSTRACT
In this work, the post-combustion CO2 capture performance was explored in 100.000 g nonaqueous solution, 30 wt % monoethylethanolamine (EMEA) and 70 wt % diethylethanolamine (DEEA). Porous solids (multi-walled carbon nanotubes (MWCNTs), silica gel (SG) and MCM-41) with different solid loadings (0.025, 0.050, 0.100 and 0.200) g were added into pure nonaqueous solution forming new absorbents to improve CO2 capture performance. The CO2 absorption (313 K) and desorption (383 K) of new absorbents were operated in absorption-desorption apparatus under atmospheric pressure. The results show that the addition of porous solids in nonaqueous solution leaded to a 2% decrease in absorption loading while contributing to a 10 minutes decrease in desorption time under same desorption extent, besides, the
