Bei der technischen Gewinnung von Wasserstoff nach dem bekannten Prozeß, Wasserdampf durch Eisen bei erhöhter Temperatur, zu zersetzen und das entstehende EisenoxydIn the technical production of hydrogen according to the known process, water vapor by iron at elevated temperature, to decompose and the resulting iron oxide
.5 durch die Einwirkung reduzierender Gase wieder in metallisches Eisen bzw. Eisenoxydul zu verwandeln und zur weiteren Darstellung von Wasserstoff geeignet zu machen, kommt es in erster Linie darauf an, das Eisen in einer.5 by the action of reducing gases back into metallic iron or iron oxide transform it and make it suitable for the further representation of hydrogen, it comes in first and foremost, the iron in one
ίο Form zur Anwendung zu bringen, welche möglichst reaktionsfähig ist und seine möglichst oftmalige Benutzung gestattet.ίο form to apply which is as reactive as possible and allows it to be used as often as possible.
Die bisher verwendeten Eisenmassen entsprachen diesen Forderun gen nur un vollkommen.The iron masses used so far met these requirements only imperfectly.
Es wurde nun gefunden, daß die Wasserstoffdarstellung im Dauerbetrieb ohne Schwierigkeiten gelingt, wenn man von einem porösen oder schwammigen Eisen ausgeht, welches durch Reduktion von Eisenerzen oder Eisenoxyden beliebiger Herkunft unter Einbettung in Kohle und äußerer Erhitzung gewonnen wurde. Ein vorzüglich geeignetes Produkt ist z. B. der aus sogenanntem Eisenschlieg in der angegebenen Weise erhaltene Eisenschwamm, wie er gemäß »Stahl und Eisen« 1911, Heft 34,It has now been found that the hydrogen representation in continuous operation is possible without any difficulties, if one starts from a porous or spongy iron, which has been obtained by reduction of iron ores or iron oxides of any origin under embedding in coal and external heating. A particularly suitable product is z. B. the sponge iron obtained from so-called Eisenschlieg in the specified manner, as described in "Steel and Iron" 1911, No. 34,
S. 1391 u. ff. in Schweden hergestellt wird und von dort als schwedischer Eisenschwamm in den Handel kommt. Es können aber auch andere in der angegebenen Weise gewonnene Eisensorten von ähnlichen Eigenschaften verwendet werden.S. 1391 et seq. Is made in Sweden and from there as a Swedish sponge iron on the market. But there can also be others obtained in the manner indicated Iron grades of similar properties are used.
Diese Eisenschwammsorten zeichnen sich bei der Verwendung zur Herstellung von Wasserstoff dadurch aus, daß sie nach kurzer Benutzung sehr hart werden, aber trotzdem dauernd sehr porös und reaktionsfähig sind.These types of sponge iron excel when used for the production of Hydrogen is characterized by the fact that they become very hard after a short period of use, but still are permanently very porous and reactive.
