    摘要: An electrolytic process and apparatus which can operate in a hydrogen reaction chamber at a hydrogen reaction rate corresponding to the increase in the rate of production of hydrogen accompanying the increase in the electrolysis rate and maintain the current efficiency at a very high value with respect to the electrolytic current for producing hydrogen and a process for the production of an electrode for this purpose. An electrolytic process is provided which comprises effecting electrolysis of an electrolytic solution in an electrolytic chamber separated from a reaction chamber by a hydrogen-storing metal member with one surface of the hydrogen-storing metal member as a cathode opposing an anode so that hydrogen thus produced is adsorbed by the hydrogen-storing metal member while allowing hydrogen thus adsorbed and a material to be treated to undergo continuous catalytic reaction in the reaction chamber on the other surface of the hydrogen-storing metal member to cause hydrogenation or reduction reaction by hydrogen thus adsorbed, wherein an electrolytic apparatus having a porous catalyst layer provided on the catalytic reaction surface of the hydrogen-storing metal member is used. The porous catalyst layer is obtained by reducing metal cations in an electroless plating solution by active hydrogen desorbed from a hydrogen-storing metal so that the hydrogen-storing metal is plated with the metal.

    摘要: An on-site process and apparatus for producing hydrogen peroxide at a high efficiency substantially from brine and oxygen-containing gas alone as raw materials while removing alkaline earth metals. Sea water concentrated by an electrodialytic apparatus 2 or the like as a raw material is supplied to an impurity removing apparatus 10 where caustic soda produced in an acid-alkali producing apparatus 11 at a subsequent stage and/or carbon dioxide gas is added to remove alkaline earth metals contained in sea water in the form of a hydroxide or carbonate precipitate. Separately, the acid-alkali producing apparatus 11 performs a salt separating operation to produce caustic soda which is then supplied to a hydrogen peroxide generator 28 to produce an alkaline aqueous solution of hydrogen peroxide.

    摘要: A method of electrolytically producing acid water using an electrolytic cell partitioned by a cation-exchange membrane into an anode chamber and a cathode chamber. Chloride ion which generates hypochlorous acid by anodic oxidation is supplied to the cathode chamber without directly supplying chloride ion to the anode chamber. Part of the chloride ion permeates from the cathode chamber into the anode chamber through the cation-exchange membrane. The chloride ion which permeates through the cation-exchange membrane is present at the surface of an anode closely adhering to the cation-exchange membrane in the anode chamber or only in the vicinity of the anode, and is efficiently anodically oxidized to form hypochlorite ion. Also disclosed is an electrolytic cell for carrying out the method of electrolytically producing acid water.

    摘要: A gas-diffusion cathode disposed in contact with an ion-exchange membrane partitioning an electrolytic cell into an anode chamber and a cathode chamber, wherein at least one guide piece is disposed in the gas-diffusion cathode and a salt water electrolytic cell using the above-described gas-diffusion cathode. By using the above-described gas-diffusion cathode for salt water electrolysis, an aqueous caustic alkali solution formed descending in the direction of gravity in the cathode changes direction of movement by contact with a guide piece, whereby the decreased electrode performance resulting from the hindrance of the supply of raw material gas and the discharge of the gas formed caused by the retention of the descending caustic alkali solution is prevented and a large-sized electrolytic cell can be used without problems generally encountered in conventional electrolytic systems.
