Description
In der letzten Zeit werden große Mengen von Gemischen von Stickstoff und Wasserstoff verbraucht; es sind infolgedessen viele Vorschläge zur Gewinnung dieser Gase gemacht worden.Lately large amounts of mixtures of nitrogen and hydrogen have been used consumed; as a result, many proposals have been made for the recovery of these gases been.
Gegenstand vorliegender Erfindung ist ein Verfahren, das ermöglicht, in besonders vorteilhafter Weise Gemische von Wasserstoff und Stickstoff darzustellen, da hierzu nur Wasser und Luft und als Reduktionsmittel in der Natur vorkommende Sulfide, Kiese, Blenden usw. erforderlich sind.The present invention is a method that enables particularly advantageous Way to represent mixtures of hydrogen and nitrogen, as only water and air and as a reducing agent Naturally occurring sulphides, gravel, blends, etc. are required.
Das Verfahren ist dadurch gekennzeichnet, daß man unter Benutzung an sich bekannter Reaktionen, einerseits den Wasserstoff durch Einwirkung von Wasser auf Sulfide, z. B. Kiese, Blenden, bei erhöhter Temperatur, anderseits den Stickstoff durch Einwirkung von· Luft auf Sulfide bei erhöhter Temperatur gewinnt, wobei die durch die Reaktionen entstehenden Schwefligsäuregase je für sich in Basen, z. B. Kalk, Ammoniak, zu Sulfiten gebunden werden, und. hierauf mittels dieser Sulfitlösungen, insbesondere des Ammoniumsulfits, die letzten Spuren des Sauerstoffs aus dem zuvor enthaltenen Stickstoffgas wegnimmt. Dieses Verfahren stellt eine Kombination mehrerer an sich, bekannter Vorgänge dar, durch deren Vereinigung ein bedeutender technischer Fortschritt erzielt wird.The method is characterized in that one uses known per se Reactions, on the one hand, the hydrogen by the action of water on sulfides, z. B. Gravel, blends, at elevated temperature, on the other hand the nitrogen through action from · air to sulphides at elevated temperature wins, which by the reactions sulphurous acid gases produced in bases, e.g. B. lime, ammonia, to sulfites be bound, and. then by means of these sulfite solutions, in particular ammonium sulfite, removes the last traces of oxygen from the previously contained nitrogen gas. This method is a combination of several known processes through the combination of which a significant technical advance is achieved.
Unter Anwendung von Schwefelkies kann das Verfahren beispielsweise wie folgt durchgeführt werden:Using pebbles, the method can be carried out, for example, as follows will:
Schwefelkies wird mit Wasser bei hoher Temperatur behandelt. Hierdurch erhält man Eisenoxyd und ein Gasgemisch, bestehend aus Schwefeldioxydi und Wasserstoff. Dies Gasgemisch wird dadurch von Schwefeldioxyd befreit, daß es über Wasser oder Basen, wie ·ζ. B. Kalk, geleitet wind. Das 4" Schwefeldioxyd wird absorbiert, während reines Wasserstoffgas unabsofbiert zurückbleibt. Pebbles are treated with water at a high temperature. This gives you Iron oxide and a gas mixture consisting of sulfur dioxide and hydrogen. this The gas mixture is freed from sulfur dioxide by pouring it over water or Bases, such as · ζ. B. Lime, headed wind. The 4 " Sulfur dioxide is absorbed, while pure hydrogen gas remains unabsorbed.
In einem anderen Apparat wind Schwefelkies mittels eines möglichst geringen Luft- +5 Überschusses geröstet. Man erhält hierdurch Eisenoxyd und ein Gasgemisch', hauptsächlich bestehend aus Schwefeldioxyd und Stickstoff. Die Gase werden, wie oben angegeben, von Schwefeldioxyd befreit, wodurch man mit Sauerstoff verunreinigtes Stickstoffgas erhält. Dieser sauerstoffhaltige Stickstoff wird mit dem erhaltenen Sulfit behandelt, wodurch der Sauerstoff unter Bildung von Sulfat absorbiert und reines Stickstoffgas erhalten wird.In another device, pebbles are blowing roasted with as little air +5 excess as possible. This gives you Iron oxide and a gas mixture, consisting mainly of sulfur dioxide and nitrogen. The gases are, as indicated above, freed from sulfur dioxide, whereby one receives nitrogen gas contaminated with oxygen. This oxygen-containing nitrogen is treated with the obtained sulfite, whereby the oxygen with the formation of sulfate absorbed and pure nitrogen gas is obtained.
Der so gewonnene Stickstoff wird mit dem Wasserstoff gemischt, welcher wie ofren angegeben erhalten worden ist, und man erhält ein Gemisch, welches für die Ammoniaksyn-The nitrogen obtained in this way is mixed with the hydrogen, which is stated as open has been obtained, and a mixture is obtained, which for the ammonia syn-
these Anwendung finden kann, während man als Nebenprodukt Schwefeldioxyd erhält.This application can be found while sulfur dioxide is obtained as a by-product.
