Electrochemical cell and method

摘要

An electrochemical cell and method whereby a reactive metal anode is contacted with an aqueous electrolyte containing the hydroxide of the anodic metal, and the electrolyte is circulated to a scrubber for contact with carbon dioxide. In the scrubber, the precipitable carbonate of the anodic metal is formed, thereby reducing the metal hydroxide concentration in the electrolyte. The metal carbonate is separated from the electrolyte and the electrolyte is recirculated to the cell.
