Carbon dioxide capture using phase change ionic liquids
Abstract
Disclosed herein are methods for CO2 capture that use phase change ionic liquids (PCILs) to remove the CO2 from flue gas or other gas streams containing CO2. PCILs have high CO2 uptake and form a liquid PCIL-CO2 complex when they react with C( )2. When the liquid PCIL-CO2 complex is heated to regenerate the solid PCIL material by removing the carbon dioxide, part of the heat needed to release the CO2 can be supplied by the heat of fusion of the PCIL as it solidifies. Utilization of the heat of fusion of the PCIL to assist in its own regeneration can substantially reduce the parasitic energy loss associated with post-combustion CO2 capture.
