Verfahren zur Gewinnung von WasserstoffProcess for the production of hydrogen
Die Erfindung betrifft ein Verfahren zur Gewinnung von Wasserstoff aus Wasser in einem mehrstufigen Kreislaufprozess.The invention relates to a method for the production of hydrogen from water in a multi-stage cycle process.
Im Hinblick auf die erhöhten Anforderungen zur Bereitstellung von Energie sind in letzter Zeit Verfahren zur Gewinnung von Wasserstoff untersucht worden, bei denen in mehrstufigen Kreislaufprozessen aus Wasser durch Umsetzungen mit insbesondere anorganischen Metallsalzen, z. B. Eisen- oder Kupferverbindungen, unter gleichzeitigem Einsatz von Anionen z. B. Schwefel oder Halogen, Wasserstoff erzeugt wird. Das Auffinden geeigneter derartiger Kreislaufprozesse, die meist vier Stufen oder mehr umfassen, ist kompliziert. Es wurden bisher daher auch nur wenige solche Reaktionsfolgen beschrieben (DOS 2 IO5 369; DOS 2 321 737), in denen zumeist Eisenverbindungen mit Halogen zum Einsatz kommen. Auch die Anwendung von anorganischen Magnesiumverbindungen, z. B. Magnesiumchlorid, als Hilfsstoffe bei der Durchführung der £reislaufprozesse ist bereits beschrieben worden. Es wurden bisher nurIn view of the increased requirements for the provision of energy, there have recently been processes for the production of hydrogen have been investigated in which in multi-stage circulatory processes from water through reactions with, in particular, inorganic Metal salts, e.g. B. iron or copper compounds, with the simultaneous use of anions z. B. sulfur or halogen, Hydrogen is generated. Finding suitable such circulatory processes, which usually comprise four stages or more, is complicated. So far, therefore, only a few such reaction sequences have been described (DOS 2 IO5 369; DOS 2 321 737) in which mostly iron compounds with halogen are used. The use of inorganic magnesium compounds, e.g. B. Magnesium chloride, as an aid in carrying out the rice flow processes has already been described. So far only

aufeinander abgestimmte engumrissene Reaktionsfolgen zur Anwendung bei der Zersetzung von Wasser vorgeschlagen.closely defined reaction sequences coordinated with one another for application suggested in the decomposition of water.
Es wurde jetzt gefunden, dass eine solche Begrenzung nicht erforderlich ist, sondern dass es bestimmte Grundreaktionen gibt, deren Durchführung eine erhebliche Flexibilität bei der Auswahl der Reaktionsfolgen für die Kreislaufprozesse erlaubt. Dementsprechend wird erfindungsgemäss ein Verfahren zur Gewinnung von Wasserstoff aus Wasser durch Umsetzung mit anorganischen Metallsalzen sowie Halogen bzw. Schwefel als Anion in Kreislaufprozessen mit mindestens drei Prozeßstufen vorgeschlagen, bei dem man in einer der Prozeßstufen Mangan(III)-oxid bildet, indem man Manganoxid in Gegenwart von Halogen bzw. Halogenwasserstoff oder ManganfII)-halogenid in Gegenwart von* Sauerstoff bzw. Wasser umsetzt. It has now been found that such a limitation is not necessary is, but that there are certain basic reactions, the implementation of which a considerable flexibility in the selection the reaction consequences for the circulatory processes allowed. Accordingly is according to the invention a process for the production of hydrogen from water by reaction with inorganic metal salts as well as halogen or sulfur as anion in circulatory processes Proposed with at least three process stages, in which one forms manganese (III) oxide in one of the process stages by Manganese oxide in the presence of halogen or hydrogen halide or manganese (II) halide in the presence of * oxygen or water.
Durch die Einschaltung derartiger Reaktionen ist es möglich, den Kreislaufprozess in mehreren Varianten aufzubauen, so dass die enge Beschränkung auf eine ganz bestimmte Reaktionsfolge, wie sie bisher vorgeschrieben wurde, entfällt.By including such reactions, it is possible to build up the cycle process in several variants, so that the narrow restriction to a very specific sequence of reactions, as previously prescribed, is no longer applicable.
Man wird im allgemeinen bestrebt sein, mit möglichst wenig Reaktionsschritten den Verfahrenskreislauf zu schliessen. Es kann aber gegebenenfalls zweckmässig sein, auf mehr Reaktionsfolgen auszuweichen, wenn anderenfalls der Aufwand für den Gesamtprozess zuIn general, efforts will be made to have as few reaction steps as possible to close the procedural cycle. However, it may be useful to use more reaction sequences, if otherwise the effort for the overall process increases

The implementation of all process stages in which there are In principle, the known thermodynamically possible reactions are carried out in the usual way.
Als Beispiele für die erfindungsgemässe Prozeßstufe seien folgende Umsetzungen genannt:The following are examples of the process stage according to the invention Implementations called:
3 MnO + Br2 - Mn3O3 + MnBr2 Mn3O^ + 2 HCl = Mn2O3 + MnCl2 + H3O3 MnO + Br 2 - Mn 3 O 3 + MnBr 2 Mn 3 O ^ + 2 HCl = Mn 2 O 3 + MnCl 2 + H 3 O
4 MnCl2+ 3 O2 = 2 Mn2O3 + 4 Cl2 MnCl2 + H2O + MnO2 = Mn3O3 + 2 HCl4 MnCl 2 + 3 O 2 = 2 Mn 2 O 3 + 4 Cl 2 MnCl 2 + H 2 O + MnO 2 = Mn 3 O 3 + 2 HCl
Mit Hilfe derartiger Reaktionen ist in verschiedener Weise die Abspaltung von Wasserstoff aus Wasser möglich, z. B. über die Zwischenstufe Mangansulfid.With the help of such reactions, the elimination of hydrogen from water is possible in various ways, eg. B. about the Intermediate manganese sulfide.
