요약

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.

대표청구항

1. A method of removing carbon dioxide from a mixed gas stream, comprising: passing a stream of gas comprising carbon dioxide through a first vessel containing an absorbent comprising a PCIL, wherein the PCIL changes phase upon reaction with the carbon dioxide to form a liquid PCIL-CO2 complex;transporting the liquid PCIL-CO2 complex to a regenerator;heating the liquid PCIL-CO2 complex in the regenerator to produce carbon dioxide gas and regenerate the solid PCIL; andtransporting the solid PCIL back to the first vessel.
