Abstract (en)

[origin: WO2014100828A1] 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.
