  • a metal reaction is used with water, in particular aluminum, which usually forms a passivating film on the surface.
  • the invention is aimed at solving the problem of eliminating this passivating film by placing aluminum in a medium that prevents the formation of an oxide film, and the use of liquid gallium, indium or their alloys is proposed as this medium.
  • a passivating agent When aluminum is placed in water in the presence of a passivating agent, a reaction begins, as a result of which hydrogen is released. Direct use of the obtained hydrogen is envisaged.

  • the obtained alkali metal hydroxide is mixed with hydrochloric acid in order to obtain alkali metal chloride.
  • Alkali metal chloride as a by-product of hydrogen production, is heated in the presence of aluminum to 300–950 ° C to reduce the alkali metal and produce aluminum chloride.
  • aluminum chloride is mixed with water in order to obtain hydrochloric acid and aluminum hydroxide, which then restore the electrolysis reactions.
  • this invention allows to obtain hydrogen immediately before its use from regenerable starting materials.
  • the main disadvantage of this method is the use of hydrochloric acid, the vapors of which are toxic, as well as the use of high temperature to carry out the reaction between metal chloride and aluminum, which creates additional energy costs, and a rather long and complicated technological process of chemical regeneration of the starting materials, which includes a lot of stages.
  • the technical problem solved by the invention is to eliminate the emission of harmful substances during the hydrogen production cycle and recovery of the starting materials, as well as simplifying the technology of regeneration of the starting materials used for the production of hydrogen.
  • the proposed method makes it possible to produce hydrogen and regenerate the starting materials without releasing harmful substances into the environment, is technologically simple and energy efficient.
  • Alkali metal hydroxide can be regenerated by electrolysis using renewable energy sources. This avoids environmental pollution.
  • Water for a controlled reaction with an alkali metal can be supplied as water vapor.
  • An oxygen-free medium is created in the container in which the alkali metal is placed.

Capacity with the formed sodium hydroxide is transported to a renewable energy source and electrolysis of sodium hydroxide is carried out.
  • Example 2 Alkaline metal - lithium is placed in a container and fill this container with an inert gas. Next, the tank is transported to the place where it is necessary to produce hydrogen. Water is dosed in a container with lithium for the controlled production of hydrogen. Hydrogen released as a result of the reaction from the reaction tank is withdrawn for direct use. The container with the formed lithium hydroxide is transported to a renewable energy source and sodium hydroxide is electrolyzed.
  • Example 3 Alkaline metal - sodium is placed in a container and fill this container with nitrogen. Next, the tank is transported to the place where it is necessary to produce hydrogen. Water is metered into a container with sodium for controlled production of hydrogen. Hydrogen released as a result of the reaction from the reaction tank is withdrawn for direct use. The electrolysis of sodium hydroxide is carried out in the same tank in which the alkali metal reacted with water.

Abstract

L'invention concerne le domaine de la production d'énergie à partir d'hydrogène et notamment la production contrôlée d'hydrogène à partir de substances de base régénérables directement avant son utilisation, qui prévoit aussi la possibilité d'utiliser des sources d'énergie renouvelables pour la régénération des substances de départ. Un métal alcalin (du sodium) est disposé dans un récipient dans lequel un vide est ensuite créé. Le récipient est ensuite transporté vers le lieu dans lequel il est prévu de produire de l'hydrogène. On ajoute en dosant de l'eau dans le récipient contenant du sodium pour produire de l'hydrogène de manière contrôlée. L'hydrogène dégagé à la suite de cette réaction est récupéré pour être utilisé directement. Le récipient contenant de l'hydroxyde de sodium ainsi formé est transporté vers une source d'énergie renouvelable pour effectuer l'hydrolyse de l'hydroxyde de sodium.
