Verfahren zum Arbeiten mit Wasserstoff oder wasserstoffhaltigen Gasgemischen unter Druck bei erhöhter Temperatur, insbesondere zur katalytischen Herstellung von Ammoniak aus den Elementen.
Beim Arbeiten mit Wasserstoff oder wasserstonhaltigen Gasgemischen in heilen, eisernen Apparaten verlieren diese bei dauernder Benutzung ihre mechanische Festigkeit und werden schliesslich unbrauchbar oder können doch, namentlich wenn sie grosse Dimensionen besitzen, nicht ohne Gefahr weiterbenutzt werden.
Im Patente Nr. 62214 ist gezeigt worden, dass man ohne Auftreten dieser Schwierigkeiten auch in eisernen Apparaten arbeiten kann, wenn man dafür sorgt, dass die Temperatur der heissen. drucktragendenEisenwandungankeinerStelle450 Cwesentlichübersteigt.
Es wurde nun gefunden, dass man den genannten Schwierigkeiten auch in der Weise begegnen

kohlenstoffreie oder kohlenstoffarme legierte Stähle verwendet.
Es hat sich ferner überraschenderweise ergeben, dass man auch solche legierte Stähle verwenden kann, welche verhältnismässig viel Kohlenstoff enthalten. Sofern nicht zu geringe Mengen der legierten Metalle, z. B. Chrom, Vanadin, Wolfram. Molybdän und dgl., vorhanden sind, bleibt die Festigkeit der Apparate überraschenderweise selbst dann erhalten, wenn beim Gebrauch infolge der Einwirkung des Wasserstoffes der Kohlenstoff zum Teil oder ganz in gasförmige Ver-

Process for working with hydrogen or hydrogen-containing gas mixtures under pressure at elevated temperature, in particular for the catalytic production of ammonia from the elements.
When working with hydrogen or hydrogen-containing gas mixtures in heal, iron apparatus, these lose their mechanical strength with continuous use and ultimately become unusable or, especially if they have large dimensions, cannot be used without danger.
In patent no. 62214 it has been shown that one can work in iron apparatus without these difficulties, if one takes care that the temperature of the hot. pressure-bearing iron wall at one point significantly exceeds 450 C.
It has now been found that the difficulties mentioned can also be countered in this way
EMI1.1
carbon free or low carbon alloy steels are used.
It has also been found, surprisingly, that alloy steels can also be used which contain a relatively large amount of carbon. Unless the amounts of the alloyed metals are too small, e.g. B. chromium, vanadium, tungsten. Molybdenum and the like are present, the strength of the apparatus is surprisingly retained even if, due to the action of hydrogen, some or all of the carbon is converted into gaseous
