N2 - In the present work, membrane contactors using both porous and nonporous polymeric hollow fiber membranes with ionic liquids as absorbent were developed for precombustion CO2 capture at elevated temperature and pressures. 1-Butyl-3-methylimidazolium tricyanomethanide [Bmim][TCM] was selected as the ILs absorbent. The compatibility and stability of six different polymeric membranes were evaluated, while the porous PTFE membrane and nonporous Teflon-PP composite membrane were considered to be the most suitable membranes for this application. Both membrane configurations were tested and showed comparable separation performances: CO2 flux values of 4.86 × 10-4 and 4.75 × 10-4 mol m-2 s-1 were obtained for the porous PTFE and nonporous Teflon-PP membrane contactor at 20 bar with a gas flow rate of 200 mL min-1, respectively. The Teflon-PP composite membrane exhibited better stability as compared to the porous PTFE membrane in a 14 day test.
