Description

Herstellung von Wasserstoff und Kohlenoxyd aus Methan Es wurde gefunden, daß man aus Methan oder methanhaltigen Gasgemischen in einfacher und vorteilhafter Weise ein Kohlenoxvd-Wasserstoff-Gemisch erhalten kann, wenn man die Ausgangsgase bei höheren Temperaturen auf Oxyde von Metallen, die in niedere Oxvde überzugehen vermögen, mit Ausnahme der Oxyde der Eisenmetalle (Eisen, Nickel, Kobalt), einwirken läßt. Dabei spaltet sich der Wasserstoff des Methans als solcher ab, während der Kohlenstoff des Methans reduzierend auf das Metalloxyd wirkt und in Kohlenoxyd übergeht. Das entstandene niedere Oxyd kann man sodann mit Sauerstoff abgebenden Stoffen, insbesondere Gasen oder Dämpfen, wie Luft, Wasserdampf oder Kohlensäure, wieder in die höhere Oxydationsstufe überführen, wobei man in den genannten speziellen Fällen Stickstoff bzw. Wasserstoff bzw. Kohlenoxyd erhält.Production of hydrogen and carbon oxide from methane It was found that from methane or methane-containing gas mixtures in a simpler and more advantageous manner Way, a carbon dioxide-hydrogen mixture can be obtained if the starting gases are used at higher temperatures on oxides of metals, which transform into lower oxides with the exception of the oxides of ferrous metals (iron, nickel, cobalt) leaves. The hydrogen of the methane splits off as such, during the The carbon of the methane has a reducing effect on the metal oxide and changes into carbon oxide. The resulting lower oxide can then be mixed with oxygen-releasing substances, in particular gases or vapors, such as air, water vapor or carbonic acid, again transfer to the higher oxidation stage, with one in the mentioned special Cases nitrogen or hydrogen or carbon oxide is obtained.

Als zu verwendende Oxyde seien diejenigen des Titans und Chroms besonders hervorgehoben. Um ein allmähliches Zerfallen der Oxyde zu Pulver zu vermeiden, kann es von Vorteil sein, sie mit unter den Arbeitsbedingungen beständigen festen Stoffen, wie Magnesiurnoxyd, Aluminiumoxyd usw., zu versetzen; die so hergestellten festen, zusammenhaltenden Massen bleiben auch bei längerem Gebrauch unverändert. Das Verfahren wird zweckmäßig bei Temperaturen zwischen etwa 6oo° und goo° ausgeführt. Man kann unter gewöhnlichem oder erhöhtem Druck arbeiten. Beispiel t Über körniges Titandioxyd wird bei 8oo° Methan geleitet. Es entsteht ein Gasgemisch, das im wesentlichen aus Wasserstoff und Kohlenoxyd im Verhältnis 2 : r besteht und nur noch 3 bis 5 °/o Methan enthält. Das dabei gebildete niedere Titanoxyd wird bei Rotglut mit Luft behandelt, wodurch es in das zur Umsetzung weiterer Mengen Methan geeignete Titandioxyd übergeführt wird. Die Regenerierung des Oxyds mit Luft läßt sich leicht so durchführen, daß das dabei erhaltene Gas im wesentlichen aus Stickstoff besteht und beispielsweise nur noch 2 °/o Sauerstoff enthält. Beispie12 Aus ungefähr gleichen Teilen Chromoxyd und Magnesiumoxyd stellt man durch Ansteigen mit Wasser, Trocknen und Zerkleinern des entstandenen Kuchens Brocken her und leitet über diese bei 750° ein methanhaltiges Gasgemisch. Das Methan wird dabei praktisch vollständig in Wasserstoff und Kohlenoxyd zerlegt. Über die verbleibende graue Oxydmasse;-leitet iriän-bei 8öä,° Wasserdampf, wobei praktisch reiner Wasserstoff entsteht und die Oxydinässe in den für eine erneute Methanumsetzung gebrauchsfertigen Zustand übergeführt wird.Particularly suitable oxides are those of titanium and chromium highlighted. In order to avoid a gradual disintegration of the oxides into powder, can it may be advantageous to cover them with solid substances that are stable under the working conditions, such as magnesium oxide, aluminum oxide, etc., to be added; the solid, cohesive masses remain unchanged even after prolonged use. The procedure is expediently carried out at temperatures between about 600 ° and goo °. One can work under normal or increased pressure. Example t About granular titanium dioxide is passed at 8oo ° methane. The result is a gas mixture which essentially consists of Hydrogen and carbon oxide exist in the ratio 2: r and only 3 to 5 per cent Contains methane. The lower titanium oxide formed in the process becomes red hot with air treated, whereby it is suitable for the implementation of further amounts of methane titanium dioxide is convicted. The regeneration of the oxide with air can easily be carried out that the gas obtained consists essentially of nitrogen and, for example contains only 2% oxygen. Example12 From approximately equal parts of chromium oxide and magnesium oxide is obtained by increasing it with water, drying and grinding of the resulting cake chunks and passes through this at 750 ° a methane-containing Gas mixture. The methane is practically completely converted into hydrogen and carbon oxide disassembled. Over the remaining gray oxide mass; -ducts iriän-at 8öä, ° water vapor, whereby practically pure hydrogen arises and the oxydinasses in the for a renewed Methane conversion is converted to the ready-to-use state.
