Abstract
Apparatus for reducing oxalic acid to a product includes a cell. A separator which separates the cell into two chambers; a catholyte chamber and an anolyte chamber. Each chamber has an inlet and an outlet. A porous cathode having a catalyst is arranged within the catholyte chamber so that an aqueous catholyte, having ammonium chloride, entering the inlet of the catholyte chamber will pass through the cathode. A porous anode is arranged within the anolyte section so that an aqueous electrolyte, having ammonium chloride, entering the inlet of the anolyte section will pass through the anode and exit through the outlet of anolyte section. A source provides the catholyte which is a mixture of oxalic acid and an aqueous electrolyte, having ammonium chloride, to the inlet of the catholyte chamber while another source provides the electrolyte to the inlet of the anolyte chamber. A d.c. voltage is provided between the cathode and the anode so as to cooperate in the reduction of oxalic acid within the porous cathode to a product which exits the catholyte chamber by way of its outlet.
