Description

Reinigung von Gasen von organisch gebundenem Schwefel Nachstehende Erfindung betrifft ein Verfahren zur Reinigung von Gasen, vorzugsweise von organischen Schwefelverbindungen; jedoch soll dabei die Zusammensetzung des Gases, beispielsweise des Wassergases, nicht in anderer Weise katalytisch verändert werden, wie es Eisen, Kobalt und Nickel tun, die bereits für diesen Zweck von anderer Seite vorgeschlagen sind. Es wurde -gefunden, daß Gold und Silber die geforderten Eigenschaften zeigen, wenn sie in einer der üblichen Arten mit großer Oberfläche und in feiner Verteilung als Kontaktsubstanzen benutzt werden. Gegenüber Blei und Antimon, die für denselben Zweck vorgeschlagen sind, haben die neuen Kontakte den Vorteil, daß sie bei erheblich niedrigeren Temperaturen von etwa zoo bis 300° schon wirksam sind. Der Vorgang ist jedoch derselbe, es wird anscheinend erst durch Reaktion des Kontaktmetalls mit den organischen Schwefelverbindungen ein Metallsulfid gebildet, das darauf durch Wasserstoff unter Bildung von Schwefelwasserstoff wieder reduziert wird. Das Verfahren kann bei gewöhnlichem, vermindertem oder beliebig erhöhtem Druck ausgeführt werden.Purification of gases from organically bound sulfur The invention relates to a method for cleaning gases, preferably organic Sulfur compounds; however, the composition of the gas should be, for example of the water gas, cannot be catalytically changed in any other way, such as iron, Cobalt and nickel do that already suggested for this purpose by others are. It has been found that gold and silver show the required properties if they are in one of the usual types with a large surface area and finely distributed be used as contact substances. As opposed to lead and antimony, which are for the same Purpose proposed, the new contacts have the advantage that they are significantly lower temperatures of about zoo to 300 ° are already effective. The process is but the same, apparently only through reaction of the contact metal with The organic sulfur compounds formed a metal sulfide, which was then put through Hydrogen is reduced again with the formation of hydrogen sulfide. The procedure can be carried out at ordinary, reduced or any increased pressure.

Ausführungsbeispiel Asbestfasern werden mit Silbernitrat imprägniert, getrocknet und geglüht und dann in geeignete Rohre oder sonstige Gefäße gebracht und auf aoo bis 300° erhitzt. Hierauf wird Wassergas durchgeleitet, das zwar von Schwefelwasserstoff, nicht aber von den organischen Schwefelverbindungen befreit ist. Zunächst findet eine Reduktion des Silberoxyds statt, und dann beginnt die katalytische Wirksamkeit, die sich dadurch bemerkbar macht, daß ohne bemerkenswerte Volumänderung das austretende Gas intensiv nach Schwefelwasserstoff riecht. Entfernt man den Schwefelwasserstoff in der üblichen Weise, so ist das so behandelte Gas frei von sämtlichen organischen Schwefelverbindungen.Embodiment Asbestos fibers are impregnated with silver nitrate, dried and annealed and then placed in suitable tubes or other vessels and heated to aoo to 300 °. Then water gas is passed through, although from Hydrogen sulfide, but not freed from the organic sulfur compounds is. First there is a reduction in the silver oxide, and then it begins catalytic effectiveness, which is noticeable without being noticeable Change in volume, the escaping gas has an intense smell of hydrogen sulfide. Removed If the hydrogen sulfide is used in the usual way, the gas thus treated is free from all organic sulfur compounds.
