AI Technical Summary
Existing electrochemical CO2 reduction processes face challenges in product purification, including high energy consumption, emissions, and inefficiencies in separating supporting electrolytes and high-boiling impurities, leading to poor process economics and low catalyst efficiency.
Implementing electrochemical separation technologies, such as electrodeionization (EDI) and resin-wafer electrodeionization (RW-EDI), to purify CO2 reduction product streams by removing ionic species and supporting electrolytes, using modified EDI cells with ion-exchange membranes to achieve high-purity products.
Achieves efficient and cost-effective purification of CO2 reduction products, reducing energy consumption and emissions, enabling the production of high-purity commodities like MEG, and potentially lowering production costs by up to 63%, with a carbon-negative impact.
