 A novel CO 2 ‐selective synthesized amine‐impregnated cross‐linked polyvinylalcohol/glutaraldehyde membrane: fabrication, characterization, and gas permeation studyAbtin Ebadi Amooghin, Mona Zamani Pedram, Mohammadreza Omidkhah and Reza Yegani Greenhouse Gases: Science and Technology, 2013, vol. 3, issue 5, 378-391 Abstract: In this paper, polyvinyl alcohol (PVA) membranes impregnated with amines (monoethanolamine and diethanolamine) were prepared for CO 2 /N 2 separation. The cross‐linking of DEA impregnated PVA by glutaraldehyde (GA) with different mass ratios (GA/PVA: 0.5, 1, 3, 5, 7%) were investigated with no use of acid catalyst or organic solvents. The effects of the amine type‐concentration, cross‐linking agent content, and feed pressure as well as stability were examined in both pure and mixed gases. Generally, CO 2 /N 2 performance through the DEA‐PVA membranes was higher than that of MEA‐PVA membranes. The fabricated membranes were characterized by differential scanning calorimetry (DSC), Fourier transform infrared (FTIR) and scanning electron microscopy (SEM). The cross‐linked membranes showed reasonable CO 2 /N 2 permselectivities in comparison with uncross‐linked membranes and these are recommended for high performance membrane for CO 2 /N 2 separation. The best‐yielding membranes (DEA‐PVA/GA(1 wt%)/PTFE) represented the greatest CO 2 /N 2 selectivity of 122.04 and 907.06 for pure and mixed gas experiments, respectively.
