Role of Facilitated Transport Membranes and Composite Membranes for Efficient CO₂ Capture - A Review.

Rafiq, Sikander; Liyuan Deng; Hägg, May-Britt

CO2 emission from anthropogenic sources has raised global environmental concerns, and efficient reduction of these greenhouse gas emissions by capturing CO2 is recognized world-wide as very important along with the implementation of new green energy technology. Membrane technology is considered to be one of the efficient techniques to be used for CO2 capture. Among different types of membranes, mixed matrix membranes and facilitated transport membranes have gained much interest in recent years due to documented high CO2 permeance through these membranes, especially when the gas is humid as is the case for flue gas from combustion. In the current review, a comprehensive discussion is focused on the development of hybrid membranes involving the selection of the fixed site carrier (FSC) membranes and the interaction of nanosilica-particles in a polymer membrane for efficient CO2 capture. Other facilitated transport membranes and mixed matrix membranes are also briefly discussed.
