Abstract
Abstract With the development of the petrochemical industry, the demand for light olefins is rapidly increasing. The separation of olefin/paraffin by membrane technology can save energy consumption and improve separation efficiency. This article reviews the latest progress in facilitated transport membranes for olefin/paraffin separation. The separation mechanism and common types of facilitated transport membranes are briefly introduced. Meanwhile, the mechanism of carrier deactivation and the corresponding strategies to improve the stability of the membranes are summarized. In concluding, current developments regarding facilitated transport membranes are summarized and directions for future development are proposed.
