Electrochemical conversion of carbon dioxide to form an organic acid

An electrochemical process for carbon dioxide conversion comprising:

• feeding water to an electrolyzer to generate a first electrolyzed product stream comprising hydrogen and a second electrolyzed product stream comprising oxygen,
• feeding an anode reactant comprising hydrogen to an anode comprising a quantity of anode catalyst;
• feeding a cathode reactant comprising carbon dioxide to a cathode comprising a quantity of cathode catalyst;
• feeding an inlet solution feed comprising water to a central flow compartment wherein the central flow compartment comprises macroreticular resin dispersed within a void space, and wherein an average diameter of said macroreticular resin is greater than about 120% of and less than about 170% of the width of said void space;
• applying a voltage of and less than about 3.5 V between the anode and cathode;
• and
• recovering a product solution comprising formic acid from an outlet of said central flow compartment, wherein a concentration of formic acid in an aqueous product solution is greater than about 9 wt % and less than about 50 wt %,
• wherein said first electrolyzed product stream comprises said anode reactant.
