Carbon dioxide capture by facilitated transport membranes: a review

International Journal of Global Warming (IJGW), Vol. 12, No. 1, 2017

Abstract: In recent years, the increase in industrial carbon dioxide emissions has put forward serious threats in atmospheric conditions. In order to address this problem various conventional techniques are available, but they have several limitations in terms of cost and energy. Carbon dioxide capture in a post combustion scenario needs cost effective and energy efficient alternatives to the conventional technologies. In this sense, membranes attract a great deal of attention for the bulk removal of CO₂ as they offer a viable option to the established conventional techniques. In this review, the effective separation of CO₂ by facilitated transport membranes (FTMs) and their recent developments in concurrence with past research findings have been reviewed and discussed. The FTMs are grouped into different categories based on the type of the carrier. Also, the various methods of improving stability, permeability, and selectivity of FTMs are discussed scrupulously. A special emphasis is put on reviewing the process challenges and the viability of the techniques in capturing industrial CO₂ emissions. Current drawbacks in the existing research and future direction for performance development are also discussed broadly.
