  Verfahren zur Darstellung von Ammoniak durch katalytische Vereinigung von Stickstoff und Wasserstoff. 



   Es ist bekannt, dass die Elemente der Eisengruppe eine ausserordentliche Erhöhung ihrer katalytischen Wirkung bei der Darstellung von Ammoniak aus den Elementen zeigen wenn sie Oxyde, Hydroxyde, Salze oder sonstige Verbindungen von Alkalien, alkalischen Erden oder Erdmetallen oder auch andere Beimengungen enthalten. 



   Es hat sich nun gezeigt, dass das zur Eisengruppe gehörige Molybdän insofern eine besondere Stellung einnimmt, als es auch bereits ohne die genannten Zusätze eine ausgezeichnete katalytische Wirkung besitzt. Es ist hiebei nicht nötig, von reinem metallischen Molybdän auszugehen, vielmehr kann man auch   Molybdänverbindungen,   wie z. B. Molybdänoxyde,    Molybdänchloride, Ammoniummolybdate, Ammoniumphosphomolybdate,   Molybdänkarbide,   Molybdännitride,-amide,-hydrare   oder dgl. verwenden. 



   Man kann das Molybdän oder die   Molybdänverbindung   zugleich mit anderen Katalysatoren, z. B. Nickel, oder auch im Gemisch mit indifferenten Stoffen, z. B. Kohle, oder auf Trägern, wie z. B. Quarz, Schamotte, Meerschaum usw. niedergeschlagen verwenden. 



   Beispiel :
Molybdänsaures oder phosphomolybdänsaures Ammon oder Molybdänsäure wird in einem Strom reinen Ammoniakgases auf dunkle Rotglut erhitzt und die entstandene stickstoffhaltige Verbindung in den Kontaktofen eingefüllt. 



   Man kann auch die genannten Ausgangsstoffe unmittelbar in den   Kontaktofen   einbringen.

  Process for the preparation of ammonia by the catalytic combination of nitrogen and hydrogen.



   It is known that the elements of the iron group show an extraordinary increase in their catalytic effect in the production of ammonia from the elements when they contain oxides, hydroxides, salts or other compounds of alkalis, alkaline earths or earth metals or other admixtures.



   It has now been shown that molybdenum, which belongs to the iron group, has a special position insofar as it has an excellent catalytic effect even without the additives mentioned. It is not necessary to start from pure metallic molybdenum; rather, molybdenum compounds such as. B. molybdenum oxides, molybdenum chlorides, ammonium molybdates, ammonium phosphomolybdates, molybdenum carbides, molybdenum nitrides, amides, hydrars or the like. Use.



   You can use the molybdenum or the molybdenum compound at the same time with other catalysts, for. B. nickel, or in a mixture with inert substances such. B. coal, or on supports such. For example, use quartz, chamotte, meerschaum etc. in a knocked down manner.



   Example:
Molybdenum or phosphomolybdic ammonium or molybdic acid is heated to a dark red heat in a stream of pure ammonia gas and the nitrogenous compound formed is poured into the contact furnace.



   The starting materials mentioned can also be introduced directly into the contact furnace.
