Patentiert im Deutschen Reiche vom 27. März 1923 abPatented in the German Empire on March 27, 1923

Es wurde gefunden, daß man die katalytische Hydrogenisation von Oxyden des Kohlenstoffs vorteilhaft in Gegenwart der bisher für diese Zwecke noch nicht benutzten Metalle Vanadin, Niob und Tantal oder ihrer Legierungen einschließlich der Hydride, Nitride und Carbide für sich oder in Mischung miteinander oder mit anderen Verbindungen ausführen kann. Man arbeitet hierbei zweckmäßig in der Weise, daß man den Wasserstoff oder die Kohlenwasserstoffe in Gegenwart der genannten Kontaktmassen bei höheren Temperaturen und Drucken auf die Oxyde des Kohlenstoffs einwirken läßt.It has been found that the catalytic hydrogenation of oxides of carbon advantageous in the presence of metals that have not yet been used for these purposes Vanadium, niobium and tantalum or their alloys including hydrides and nitrides and carbides can run alone or in admixture with one another or with other compounds. One works here expediently in such a way that the hydrogen or the hydrocarbons in the presence of the contact materials mentioned allows higher temperatures and pressures to act on the oxides of carbon.

Beispielexample

Durch ein Hochdruckrohr, das mit kleinstückigem Vanadinmetall beschickt ist, wird bei 500 bis 600 ° und 800 Atm. Druck ein reines, trockenes Gemisch von 80 Teilen Wasserstoff und 20 Teilen Kohlenöxyd geleitet. In der Vorlage scheiden sich reichliche Mengen Methylalkohol u. dgl. ab.Through a high pressure pipe that is filled with small pieces of vanadium metal at 500 to 600 ° and 800 atm. Pressure a pure, dry mixture of 80 parts of hydrogen and 20 parts of carbon dioxide. Plenty of quantities differ in the original Methyl alcohol and the like.

Statt des Vanadins kann man z. B. auch Niob oder Tantal, letzteres beispielsweise in Fadenform, verwenden. Es können auch weitere Metalle, Oxyde usw. zugegen sein. Die Metalle Vanadin, Niob und Tantal gehen bei der beschriebenen Arbeitsweise nicht merklich in Oxyde über, sondern bleiben praktisch unverändert.Instead of vanadium you can z. B. also niobium or tantalum, the latter for example in Thread shape. Other metals, oxides, etc. can also be present. the Metals vanadium, niobium and tantalum do not go noticeably with the described method of operation in oxides, but remain practically unchanged.

Die Verwendung der Kontaktmassen der Patente 6oo 677 und 636 682 wird hier ausgenommen. The use of the contact masses of patents 6oo 677 and 636 682 is excluded here.
