とが強く求められている。(Prior art) Chemical reactions proceed by applying energy such as temperature and pressure, but in electrochemical reactions, instead of using such energy, electricity is passed through the anode and cathode, and all the energy required for the reaction is generated. Because it relies on electrical energy, it consumes a large amount of electricity. Therefore, as power costs rise, there is a strong need to reduce power consumption.
電気化学反応には、目的とする反応に固有の理論分解電
圧に、陽極および陰極の過電圧や、電解液、隔膜等の電
気抵抗によるＩＲ酸成分加えた電解電圧が必要である。An electrochemical reaction requires an electrolytic voltage that is the sum of the theoretical decomposition voltage specific to the desired reaction, overvoltages at the anode and cathode, and IR acid components due to the electrical resistance of electrolytes, diaphragms, etc.
従って、消費電力を低下させるためには、電解電圧のう
ち理論分解電圧以外の要素である電極の過電圧やＩＲ降
下を小さくすることが必要となる。Therefore, in order to reduce power consumption, it is necessary to reduce the overvoltage and IR drop of the electrodes, which are elements other than the theoretical decomposition voltage of the electrolytic voltage.

案されている。In salt electrolysis using an ion-exchange membrane method, which is a typical electrochemical reaction carried out industrially, a nickel-based coating is formed on an iron or stainless steel cathode to lower cathode overvoltage and reduce electrical resistance. A large ion exchange membrane is used to reduce the IR drop caused by the ion exchange membrane. In addition, in salt electrolysis, in order to reduce the electrical resistance due to the gas generated at both electrodes, the structure of the electrodes is designed to allow gas to easily escape, and the ion exchange membrane is designed to prevent air bubbles from adhering to the surface of the ion exchange membrane. Forming unevenness on the surface,
(JP-A-55-110786 @, JP-A-56-11
6891), forming a layer to prevent gas from adhering (Japanese Unexamined Patent Publication No. 56-75583), and adding metals, metal ions, or organic substances to the electrolytic solution to prevent gas from adhering to the membrane surface through electrolysis. Forming a layer (JP-A-56-1)

あった。(Problems to be Solved by the Invention) The above-mentioned methods proposed for reducing the electrolytic sliding voltage are each effective, but there are problems with the production cost of the ion exchange membrane and the sustainability of the reduction in the electrolytic sliding voltage. There were problems such as impurities being mixed into the product.

目的としたものである。Fluidized bed electrolytic cells, in which the electrolytic cell is filled with conductive solid particles and the particles are made to flow to create quasi-three-dimensional electrodes, are used for recovering metals from dilute solutions, etc.
In the present invention, a small amount of conductive or non-conductive particles are dispersed in the electrolyte, and the particles do not act as electrodes, but rather promote the separation of generated gas from the electrodes and ion exchange membrane. However, the purpose is to reduce the electrolytic voltage by increasing the transfer speed of reactants and reaction products.

ないものと認められる。The electrolytic method and electrolytic cell of the present invention for dispersing solid particles in an electrode seedling are capable of obtaining an equal or higher voltage drop not only with conductive particles but also with non-conductive particles, and a gas release prevention layer. When using an ion-exchange membrane formed with It is recognized that this is not the case.

Any particles such as synthetic resin particles or particles obtained by pulverizing an ion exchange membrane can be used, and the amount of particles added and the size of the particles can also be determined arbitrarily. Further, the ion exchange membrane used for producing the particles may be an old membrane used for electrolysis.

The particles may be circulated by forced circulation means such as a pump provided outside the electrolytic cell, or by means for enhancing the natural circulation caused by the lift action of the generated gas, which may be provided inside the electrolytic cell.

Furthermore, if the effect of lowering the electrolytic voltage is reduced due to the outflow of particles, it is preferable to re-add the amount of particles that have flowed out into the electrolytic cell.
