  • Systems and methods for separation of olefins from mixtures that contain reducing agents
    Patent number: 11420916
    Abstract: The present disclosure pertains to methods and systems for separating olefins from a mixture that includes olefins and non-olefins. The methods include associating the mixture with a support that is embedded with an ionic liquid and a metal ion. The ionic liquid prevents the substantial reduction of the metal ion by reducing agents while the metal ion mediates the transport of the olefin through the support by selectively and reversibly coupling with the olefin. In some embodiments, the support may be in the form of supported ionic liquid porous membranes, and the ionic liquid may be held within the pores of the support by capillary forces. In some embodiments, the support may be in the form of a composite, and the ionic liquid may be dispersed throughout the composite. In some embodiments, the metal ion may be dissolved in the ionic liquid and dispersed throughout the support.
