Description

Electrolyzer and Electrolytic Method

The present invention relates to an electrolytic cell and a method, and more particularly, to an electrolytic cell and an electrolytic method capable of simultaneously producing an oxidant and a chemical product by simultaneously carrying out an anode reaction and a cathode reaction in one electrolyzer.

In the electrochemical reaction, the oxidation reaction occurring in the anode chamber of the electrolyzer and the reduction reaction occurring in the cathode chamber of the electrolyzer occur simultaneously.

In most electrochemical processes, the desired product is prepared through anodic or cathodic reaction, and the opposite electrode produces acid or base through electrochemical reaction of water, a solvent in solution, and these reactants are produced as by-products. It can be used for waste treatment or for separate purposes.

As shown in FIG. 1, the conductive diamond anode 10 is accommodated by the porous PTFE diaphragm 9, and the anode chamber 3 and the conductive diamond cathode 12 filled with the electrolyte solution containing the sulfate ion are accommodated. In addition, the anode chamber 3 is partitioned into a cathode chamber 4 filled with sulfuric acid at the same concentration. An anolyte solution supply port 7 is connected to the anode chamber 3, and sulfuric acid, which is an anolyte solution, is supplied to the anode chamber 3 through the anolyte solution supply port 7. In addition, a catholyte supply port 8 is connected to the cathode chamber 4, and the catholyte is supplied to the cathode chamber 4 through this catholyte supply port 8. The oxidizing substance solution produced in the anode chamber 3 is discharged to the anolyte outlet 1. In addition, hydrogen and residual sulfuric acid solution generated in the cathode chamber 4 are discharged to the cathode liquid outlet 2. When sulfuric acid and sulfates are injected into the anode chamber, peroxodisulfate is produced through the anodic reaction. Note that, in the cathode chamber the solvent in the cathode solution, H ₂ O The hydrogen (H ₂₎ and hydroxide ions (OH ^-) through the electrolysis reaction to be occurred, hydroxide ions (OH ^-) is the hydrogen ion passed after the reaction at the anode (H ⁺⁾ and the concentration of the cathode solution is controlled by the hydrogen ion (H ⁺⁾ and meet the neutralization reaction in the cathode chamber the supply of sulfuric acid (H ₂ SO _4). The generated H ₂ is mainly diluted and discarded. As such, the oxidizing substance, which is a peroxodisulfoxide produced by the anodic reaction, is produced as a desired product, and the hydroxide ions produced by the cathodic reaction are discarded by the neutralization reaction.

K ⁺ and H ⁺ in the solution phase is passed to the cathode portion through the cation membrane. Carbon dioxide is converted to formate (HCOOK) by the electrode reaction in the cathode portion. In this process, KOH is continuously supplied to the oxidation reaction part to balance the ions. In the second step, one equivalent of potassium sulfate is produced when two equivalents of formic acid are produced using sulfuric acid (H ₂ SO ₄ ). In the third step, formic acid is distilled and potassium sulfate is precipitated to separate formic acid and potassium sulfate.
