Carbon dioxide electrolysis system and method

The invention discloses a carbon dioxide electrolysis system and method. An electrolysis system for carbon dioxide includes an electrochemical electrolysis device and an absorption unit in fluid communication with the electrochemical electrolysis device. The electrochemical electrolysis device electrolyzes a cathode reactant and an anode reactant to respectively form a cathode mixture and an anode mixture. Wherein the cathode reactant comprises carbon dioxide or a compound containing bicarbonate or carbonate, the cathode mixture comprises carbon monoxide and hydrogen, and the anode mixture comprises chlorine. The absorption unit treats the cathode mixture and separates a synthesis gas including carbon monoxide and hydrogen. The electrolysis system and method of carbon dioxide can slow down the greenhouse effect, and the components of the reduction product of carbon dioxide are pure and can be recycled. 本发明公开一种二氧化碳的电解系统及方法。二氧化碳的电解系统包括一电化学电解设备以及与电化学电解设备流体连通的一吸收单元。电化学电解设备电解一阴极反应物与一阳极反应物，以分别形成一阴极混合物与一阳极混合物。其中，阴极反
