Abstract

Different types of polyethylenimine were studied to further improve the CO₂ adsorption separation performance of the novel "molecular basket". The CO₂ adsorption capacities were 153.5 and 117.2 mg/g-adsorbent for MCM PEI-L and MCM-PEI-B, respectively. The CO₂ adsorption capacity for MCM-PEI-L was 31% higher than that for MCM-PEI-B. CO₂ desorption rate for MCM-PEI-L was faster than that for MCM-PEI-B. At the beginning of the separation, CO₂ was completely adsorbed by the "molecular basket" adsorbents and the CO₂ concentration was below the detection limit of the GC. The CO₂ breakthrough capacity for MCM-PEI-L was 64% higher than that for MCM-PEI-B. Both adsorbents hardly adsorbed any N₂ and O₂.
