Verfahren zur Darstellung von Wasserstoff.
EMI1.1
Wasserstoff zn erzeugen, kann bekanntlich das entstandene Eisenoxyduloxyd wieder durch reduzierende Gase in Eisen zurückverwandelt werden, so dass man mit Hilfe beider Vor- gänge theoretisch eine unbegrenzte Menge Wasserstoff aus einer gewissen Menge Eisen gewinnen könnte.
So einfach die Reaktion theoretisch betrachtet aussieht, so schwierig gestaltet sich die Durchführung in der Praxis, insbesondere der Reduktionsprozoss.
Man kann zur Durchführung des Verfahrens von metallischem Eisen wie von Eisenoxyden ausgehen. Geht man von oxydischen Eisenerzen (Eisenglanz, Roteisenstein) aus, so treten verschiedene Übelstände auf. Entweder behält das Erz nicht die genügende Festigkeit, lerbröckelt und versperrt den Gasen den Weg, oder aber es ist infolge seiner natürlichen

und diese zur Reduktion verwendete, wobei jedoch der Übelstand auftrat, dass bei der hohen Temperatur infolge von Reaktionen der Bestandterle des Briketts untereinander die MassefürdieReduktionunwirksamwurdeodergarzusammenschmolz.
Durch Versuche ist nun gefunden worden, dass man ein ausgezeichnetes Matrial zu vorliegender Reaktion erhält, wenn man natürliches Schwl'fe1pispn (Pyrite) einer oxydierenden Kostung unterwirft, derait, dass sowohl aller Schwefel wie auch die flüchtigen : Metalle (Zink, Arsen usw.) völlig ausgetrieben werden. Das so erhaltene Material vereinigt grosse Porosität (infolge der erlittenen Volumenverminderung) mit Feuerbeständigkcit (infolge der hohen Temperatur, der es beim Rösten ausgesetzt war) und wird infolge dessen leicht reduziert und behält dabernd seine Form und Wirksamkeit. Da es frei von Zink und Arsen ist, werden spätere Verunreinigungen mit Zink bezw. dem giftigen Arsenwasserstoff, der den erzeugten Wasserstoff wertles machen würde, vermieden.
Es ist nicht ausgeschlossen, dass die in den Erzen enthaltenen Metallreste, wie Kupfer einen günstigen Einfluss auf den Verlauf des Verfahrens ausüben.

Process for the preparation of hydrogen.
EMI1.1
It is well known that the iron oxide formed can be converted back into iron by reducing gases, so that theoretically an unlimited amount of hydrogen could be obtained from a certain amount of iron with the aid of both processes.
As simple as the reaction looks theoretically, it is difficult to carry out in practice, especially the reduction process.
To carry out the process, one can start from metallic iron such as iron oxides. If one starts from oxidic iron ores (iron luster, red iron stone), then various evils arise. Either the ore does not retain sufficient strength, it crumbles and blocks the way for the gases, or it is due to its natural properties
EMI1.2
and used it for reduction, but there was a problem that at the high temperature, as a result of reactions of the constituents of the briquette with one another, the mass became ineffective for reduction or even melted together.
It has now been found through experiments that an excellent material for the reaction at hand is obtained if natural sulfuric acid (pyrite) is subjected to an oxidizing cost, so that all sulfur as well as the volatile: metals (zinc, arsenic, etc.) be driven out completely. The material thus obtained combines great porosity (due to the reduction in volume suffered) with fire resistance (due to the high temperature to which it was exposed during roasting) and is therefore slightly reduced and thereby retains its shape and effectiveness. Since it is free from zinc and arsenic, later contamination with zinc and / or. the poisonous arsine, which would make the hydrogen produced valuable, avoided.
It cannot be ruled out that the metal residues contained in the ores, such as copper, have a beneficial influence on the course of the process.
