.4.4

Für die Beleuchtung von Eisenbahnen wird in der Regel komprimiertes Ölgas verwendet, für welches man auf kostspieliges und mitunter schwer zugängliches Ausgangsmaterial angewiesen ist. Sucht man statt dessen das leicht zugängliche gewöhnliche Leuchtgas der Kohlendestillation in komprimierter Form zu verwenden, so werden die Glühstrümpfe braunfleckig, brüchig und untauglich, was, wie sich gezeigt hat, von einer geringen Eisencarbonylbildung aus dem Kohlenoxyd des Leuchtgases und dem Eisen der Gasbehälter herrührt. Das Kohlenoxyd des Leuchtgases etwa durch Waschen mit KupferchlorürlösungenCompressed oil gas is usually used for lighting railways, for which one has to rely on costly and sometimes difficult to access source material is. If you look instead for the easily accessible common luminous gas of the To use coal distillation in compressed form, so will the mantles brown spots, brittle and unsuitable, which, as has been shown, from a low formation of iron carbonyl originates from the carbon dioxide of the luminous gas and the iron of the gas container. The carbon dioxide of the luminous gas for example by washing with copper chloride solutions

!5 zu entfernen, macht mancherlei Schwierigkeiten, insbesondere des Acetylengehaltes wegen, der die Verwendung von Kupferteilen in der Apparatur sowie namentlich den Gebrauch ammoniakalischer Kupferoxydullösungen der Explosionsgefahr wegen erschwert bzw. ausschließt. Removing! 5 poses a number of difficulties, in particular because of the acetylene content, the use of copper parts in the Apparatus and especially the use of ammoniacal copper oxide solutions of the Risk of explosion due to difficult or excluded.

Es wurde nun gefunden, daß man gewöhnliches Leuchtgas leicht und ohne jede schädliche Folgen der Beleuchtung von Eisenbahnen usw. dienstbar machen kann, wenn man dasselbe zusammen mit Wasserdampf bei Temperaturen von ungefähr 400 bis 700 ° über geeignete Eisenkontaktmassen leitet, die das Kohlenoxyd unter Wasserstoffbildung in Kohlendioxyd überführen, und hierauf, gegebenenfalls nach Entfernung der Kohlensäure und des gleichzeitig entstandenen Schwefel-It has now been found that you can use ordinary luminous gas easily and without any harmful Consequences of the lighting of railroads etc. can be made subservient if one can do the same together with water vapor at temperatures of about 400 to 700 ° above suitable Conducts iron contact masses, which convert the carbon dioxide into carbon dioxide with the formation of hydrogen, and then, if necessary after removal of the carbonic acid and the simultaneously formed sulfur

Wasserstoffs, komprimiert. Eine weitere wesentliche, insbesondere schädliche Beeinflussung des Leuchtgases findet hierbei nicht statt.Hydrogen, compressed. Another significant, particularly harmful, influencing of the Luminous gas does not take place here.

Man leitet z. B. Leuchtgas (Steinkohlengas) mit 8 Prozent Kohlenoxyd zusammen mit Wasserdampf (etwa 0,3 kg auf 1 cbm Gas) bei 500 ° über eine aktivierte Eisenoxydmasse, die'z.B. gemäß Patentschrift · 279582 hergestellt wurde; das austretende Gas enthält nur höchstens 0,5 bis 1 Prozent Kohlenoxyd, welche Mengen, ' wie sich gezeigt hat, unter den in Betracht kommenden Bedingungen keine schädliche Bedeutung erlangen können. Das Gas wird gewünschtenfalls gereinigt, auf 12 Atmosphären komprimiert und in die Transportbehälter gefüllt. Der unverbrauchte Wasserdampf kann für die Wärmeregeneration mit nutzbar gemacht oder sonstwie niedergeschlagen werden.One leads z. B. coal gas (coal gas) with 8 percent carbon oxide together with Water vapor (about 0.3 kg to 1 cbm of gas) at 500 ° over an activated iron oxide mass, die'e.g. according to patent specification · 279582; the escaping gas only contains at most 0.5 to 1 percent carbon oxide, which amounts, as has been shown, among the in The conditions under consideration cannot acquire any harmful significance. That If desired, gas is cleaned, compressed to 12 atmospheres and placed in the transport containers filled. The unused water vapor can be used for heat regeneration made usable or otherwise knocked down.
