Description

Gewinnung von Wasserstoff bei niederer Temperatur durch Einwirkung von Phosphor auf Wasserdampf. Es ist bekannt, daß Phosphor bei 17o° Wasser unter Bildung von Phosphorsäure und Phosphorwasserstoff zersetzt.Extraction of hydrogen at low temperature by exposure from phosphorus to water vapor. It is known that phosphorus falls below water at 17o ° Formation of phosphoric acid and hydrogen phosphide decomposes.

Wenn man quantitativ Phosphorsäure und Wasserstoff erhalten will, muß man die Temperatur bis gegen 6oo° erhöhen, und um genügende Schnelligkeit der Reaktion zu erhalten, bis auf i ooo° oder mehr.If you want to get phosphoric acid and hydrogen quantitatively, one must raise the temperature up to about 600 °, and enough speed of the Response to obtain down to 1,000 ° or more.

Nach der Erfindung ist es möglich, die vollkommene Bildung von Phosphorsäure und Wasserstoff bei bedeutend niedrigerer Temperatur von 35o° C bis 4oo° C zu erreichen.According to the invention it is possible for the complete formation of phosphoric acid and hydrogen at a significantly lower temperature of 35o ° C to 400 ° C.

Der Grundgedanke des Verfahrens ist der, gleichzeitig zwei oder mehrere Katalysatoren einwirken zu lassen, deren einer immer aus amorpher, absorbierender Kohle und der oder die andern aus Gasen oder Dämpfen bestehen.The basic idea of the procedure is that two or more at the same time Allow catalysts to act, one of which is always amorphous, absorbent Coal and one or the other consist of gases or vapors.

Nach einer praktisch verwendbaren Ausführungsform des Verfahrens wird zu den reinen oder mit andern Gasen verdünnten Phosphordämpfen Salzsäure und Wasserdampf zugefügt, worauf sie über absorbierende Kohle geleitet werden, welche bei 350° gehalten wird.According to a practically usable embodiment of the method to the pure phosphorus vapors or those diluted with other gases, hydrochloric acid and water vapor added, whereupon they are passed over absorbent charcoal, which is kept at 350 ° will.

Da die Reaktion exotermisch ist, -wird man, um die Masse der Kohle auf dieser Temperatur zu erhalten, Gase von mehr oder minder tiefer Temperatur verwenden müssen, und zwar je nach der Menge der verwendeten Kohle und den unvermeidbaren Verlusten an Hitze durch Leitung und Ausstrahlung. Es schadet übrigens nichts, -wenn die genannte Temperatur überschritten wird, wenn die verwendeten Stoffe höhere Temperaturen vertragen können.Since the reaction is exothermic, one will get to the mass of the coal To maintain this temperature, use gases at a more or less low temperature depending on the amount of coal used and the unavoidable ones Loss of heat through conduction and radiation. Incidentally, it doesn't do any harm if the temperature mentioned is exceeded if the substances used are at higher temperatures can tolerate.

Die verwendete Salzsäure findet sich bei Kondensation der überschüssigen Dämpfe wieder, und die Phosphorsäure wird durch planmäßiges Auswaschen der Kohle zurückgewonnen.The hydrochloric acid used is found when the excess condenses Fumes again, and the phosphoric acid is systematically washed out of the charcoal recovered.

Bei einer anderen Ausführungsform des Verfahrens wird der Phosphor, um die andern Gase zu entfernen, vorher mit Kohle absorbiert, was bei 300 bis 35o° stattfinden kann, und zwar wird die mit Phosphor beladene Kohle der Behandlung durch Salzsäure und Wasserdampf unterworfen.In another embodiment of the process, the phosphorus is previously absorbed with charcoal in order to remove the other gases, which can take place at 300 to 35o °, namely the charcoal loaded with phosphorus is subjected to treatment by hydrochloric acid and water vapor.

Man kann die Salzsäure auch durch andere Säuren ersetzen.You can also replace the hydrochloric acid with other acids.
