Method and system for the electrochemical co-production of halogen and carbon monoxide for carbonylated products
First Claim
1. A method for co-producing carbon monoxide from a first region of an electrochemical cell having a cathode and a halogen from a second region of the electrochemical cell having an anode, the method comprising the steps of:
- contacting the first region of the electrochemical cell with a catholyte comprising carbon dioxide;
contacting the second region of the electrochemical cell with an anolyte comprising a recycled reactant, wherein the recycled reactant is HX, where X is selected from the group consisting of F, Cl, Br, and I; and
applying an electrical potential between the anode and the cathode of the electrochemical cell sufficient to reduce the carbon dioxide and co-produce the carbon monoxide recoverable from the first region of the electrochemical cell and the halogen recoverable from the second region of the electrochemical cell.

Abstract
The present disclosure is a system and method for producing a first product from a first region of an electrochemical cell having a cathode and a second product from a second region of the electrochemical cell having an anode. The method may include a step of contacting the first region with a catholyte including carbon dioxide and contacting the second region with an anolyte including a recycled reactant. The method may further include applying an electrical potential between the anode and the cathode sufficient to produce carbon monoxide recoverable from the first region and a halogen recoverable from the second region.
