    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 process and apparatuses for producing hydrogen peroxide which provides good current density and production efficiency from an electrolytic liquid having an exceedingly low conductivity, such as ultrapure water. An electrolytic cell main body containing an anode 5 and a cathode 6 which are electrically connected to each other via ion-exchange resin particles 9 is used to conduct electrolysis while maintaining the electrical connection. High-purity, high-concentration hydrogen peroxide is produced at a high current efficiency even when the electrolytic liquid has an exceedingly low conductivity.

    摘要: A process for the production of hydrogen peroxide solution from seawater as a starting material substantially free of effective chlorine or organic halogen compounds. An electric current is passed through an insoluble anode and an oxygen gas diffusion cathode while keeping the halide ion concentration of anolyte supplied to the anode chamber to a level not greater than 1 g/l. Hydrogen peroxide thus generated dissolves in the catholyte. Anodic oxidation of halide ions is suppressed, to thereby inhibit the production of effective chlorine.
