    Patent Number:
    US 9951008 B2
    Description:

    Some embodiments described herein relate to ionic liquids comprising an anion of a heteraromatic compound such as optionally substituted pyrrolide, optionally substituted pyrazolide, optionally substituted indolide, optionally substituted phospholide, or optionally substituted imidazolide. Methods and devices for gas separation or gas absorption related to these ionic liquids are also described herein.

    Patent Number:
    US 10086331 B2
    Description:

    Disclosed herein are methods for CO.sub.2 capture that use phase change ionic liquids (PCILs) to remove the CO.sub.2 from flue gas or other gas streams containing CO.sub.2. PCILs have high CO.sub.2 uptake and form a liquid PCIL-CO.sub.2 complex when they react with C( ).sub.2. When the liquid PCIL-CO.sub.2 complex is heated to regenerate the solid PCIL material by removing the carbon dioxide, part of the heat needed to release the CO.sub.2 can be supplied by the heat of fusion of the PCIL as …
