Facilitated transport membranes for CO2 separation and capture

Membrane separation is a promising technology for CO2 separation and capture because of the high energy efficiency, small footprint and operational simplicity. A CO2 facilitated transport membrane is an important group of membranes for CO2 separation. In this review, the facilitated transport mechanism is described in conjunction with the chemical reactions of CO2 and amine carriers. A wide range of facilitated transport membranes is discussed, including amine-based fixed-site carrier membranes, amine mobile carrier-containing membranes and other facilitated transport membranes with different types of carriers and/or inorganic fillers to further improve the performance of facilitated transport membranes. This review concludes with remarks on the future perspectives of the facilitated transport membranes for CO2 separation and capture applications.
