- Compared to the conventional technologies such as amine absorption for CO2 capture from industrial sources such as flue gas, membrane separation process has unique advantages of being environmentally benign, lower maintenance and smaller footprint. Composite membranes with high CO2 permeation rate have great potential to capture CO2 from flue gas economically competitive. This paper reports our development in composite hollow fiber membranes with ultra-thin selective layer by using ultrafiltration hollow fibres as substrate, coated with multiple layers of gutter, selective and protective layers, using commercially available (polyether (PE)-block- polyamide (PA) copolymer) Pebax® as base material for the selective layer. The optimized fabrication condition was evaluated based on screening of substrates, selection of gutter layer material as well as evaluation of the selective material and dip-coating conditions against the gas separation performance with CO2 permeance and CO2/N2 selectivity. Consistently high CO2 permeance up to 560 GPU and CO2/N2 selectivity as high as 45 were achieved with composite membranes fabricated with pure Pebax® as selective layer while improvements were further achieved with addition of nanoparticles into the selective solution for dip-coating.
