Abstract: A system and method for CO2 capture and electroregeneration and synchronous conversion are provided. The system includes a CO2 capture subsystem, which uses an absorption liquid to capture CO2 and generate a capture liquid; and a CO2 electroregeneration and synchronous conversion subsystem, including a cathode chamber provided with a cathode electrode, a sample inlet, and a sample outlet, an anode chamber having an anode electrode, a sample inlet connected to an outlet of the capture liquid of the CO2 capture subsystem, and a sample outlet connected to the sample inlet of the cathode chamber for introducing CO2 regenerated by anodic oxidation into the cathode chamber for electroreduction, and a balance chamber in the middle having a sample outlet connected to an inlet of the absorption liquid of the CO2 capture subsystem. The system can perform self-circulation and stably operate, to capture, regenerate and convert CO2.
