1. A system for the regeneration of carbon dioxide from a flue gas, the system comprising:

  • A CO2 capture system configured to receive a catalytically-enhanced solvent stream and a flue gas stream having CO2, the catalytically-enhanced solvent stream and the flue gas stream being contacted in the CO2 capture system to provide a catalytically-enhanced CO2-rich outlet stream;

    a catalyst treatment system configured to receive the catalytically-enhanced CO2-rich outlet stream from the CO2 capture system and produce a two-phase outlet solvent stream having crystals;

    a separation apparatus configured to receive the outlet solvent stream having crystals and separate the outlet solvent stream having crystals into a catalyst solvent stream and a CO2-rich non-catalyst solvent stream; and

    a CO2 regeneration apparatus configured to receive the CO2-rich non-catalyst solvent stream from the separation apparatus and produce a CO2 stream and a regenerator outlet solvent stream, the regenerator outlet solvent stream being combined with catalyst for return to the CO2 capture system as the catalytically-enhanced solvent stream.
