【 摘 要 】
References(13)Liquid membranes of triethylenetetramine mixed with ionic liquids were prepared on a hydrophobic microporous membrane using a novel nanoparticle-supported construction. A flat membrane module with the amine/ionic liquid membrane was used for the recovery of CO2 from room air. CO2 was enriched 3–5 times in the sweep air passing through the membrane module. There was an optimum amine/ionic liquid ratio of 10–25 wt% to effectively concentrate the CO2. These permeation results were analyzed in terms of permeability based on a solution–diffusion mechanism. The present membrane process for CO2 separation has proved to be reasonably durable for a greenhouse application.
