Abstract
Disclosed herein are methods for COcapture that use phase change ionic liquids (PCILs) to remove the COfrom flue gas or other gas streams containing CO. PCILs have high COuptake and form a liquid PCIL-COcomplex when they react with C( ). When the liquid PCIL-COcomplex is heated to regenerate the solid PCIL material by removing the carbon dioxide, part of the heat needed to release the COcan 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 COcapture.
