Electrochemical co-production of chemicals employing the recycling of a hydrogen halide
First Claim
1. A 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 comprising the steps of:
- contacting the first region with a catholyte comprising carbon dioxide;
contacting the second region with an anolyte comprising a recycled reactant, wherein the recycled reactant is a hydrogen halide, HX, where X is selected from the group consisting of F, Cl, Br, I, and mixtures thereof;
applying an electrical potential between the anode and the cathode sufficient to produce the first product from the first region and the second product from the second region, wherein the second product is X2;
removing the second product from the second region;
introducing the second product and at least one of an alkane, an alkene or an aromatic compound to a secondary reactor;
producing the recycled reactant through a reaction of the second product and the at least one of an alkane, an alkene or an aromatic compound; and
recycling the recycled reactant produced through the reaction of the second product and the at least one of an alkane, an alkene or an aromatic compound at the secondary reactor to the second region.

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 comprising carbon dioxide. The method may include another step of contacting the second region with an anolyte comprising a recycled reactant. The method may include a step of applying an electrical potential between the anode and the cathode sufficient to produce a first product recoverable from the first region and a second product recoverable from the second region. The second product may be removed from the second region and introduced to a secondary reactor. The method may include forming the recycled reactant in the secondary reactor.
