Method and system for production of oxalic acid and oxalic acid reduction products

摘要

The present disclosure is a method and system for production of oxalic acid and oxalic acid reduction products. The production of oxalic acid and oxalic acid reduction products may include the electrochemical conversion of CO2 to oxalate and oxalic acid. The method and system for production of oxalic acid and oxalic acid reduction products may further include the acidification of oxalate to oxalic acid, the purification of oxalic acid and the hydrogenation of oxalic acid to produce oxalic acid reduction products.

1. A method for producing oxalic acid in an electrochemical cell, the electrochemical cell including a first region having a cathode and a second region having an anode, the method comprising the steps of:
contacting the first region with a catholyte comprising carbon dioxide, an electrolyte and an aprotic solvent; contacting the second region with an anolyte, the anolyte comprising hydrogen, the electrolyte and the aprotic solvent; receiving the hydrogen in a gas stream at the second region; and applying an electrical potential between the anode and the cathode sufficient to produce oxalic acid recoverable from the second region.
