    Verfahren zur Herstellung   von Katalysatoren für die   Animoniaksynthese.   
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 in Gegenwart von Stickstoff drei Teile   pulverförmiges   Eisen, gemengt mit zwei Teilen Lithiumnitrid, auf eine Temperatur von   500-600  C   erhitzt. 



   Das vorliegende Verfahren ist für die Herstellung von   Stickstoffverbindungen   für alle bekannten gewerblichen Verwendungen solcher Stickstoffverbindungen anwendbar. 



   Es kann gleichfalls erfindungsgemäss eine wichtige Anwendung, nämlich für die Synthese von Ammoniak, finden. Es genügt tatsächlich, bei einer Temperatur von   550-600 C,   gleichgültig bei welchem Druck, ein Gemenge von Stickstoff und Wasserstoff über Eisen, welches sich in Kontakt mit Lithiumnitrid befindet (z. B. 3 Teile gepulvertes Eisen im Gemenge mit 2 Teilen   Lithiumnitrid),   in Gegenwart eines Oxydes eines Stoffes der Erdmetallgruppe, z. B. in Gegenwart von 5-10 Gewichtsprozenten Tonerde, streichen zu lassen, damit Ammoniak entstehe. 



   Man kann daher Ammoniak selbst bei verhältnismässig niedrigem Druck, z. B. von der Grössenordnung des   atmosphärischen   Druckes, erzeugen. 



   PATENT-ANSPRÜCHE :
1. Verfahren zur Herstellung von Katalysatoren für die Ammoniaksynthese, dadurch gekennzeichnet, dass man Stickstoff in   der Wärme   auf Eisen oder auf ein oder mehrere Metalle der Eisengruppe einwirken lässt, das bzw. die sich in Kontakt mit einer oder mit mehreren stickstoffenthaltenden Ver-   bindungen des   Lithiums, wie   Lithiumnitride-oder Lithium-Stickstoff-Verbindungen befinden.

    Process for the preparation of catalysts for the synthesis of animonia.
 EMI1.1
 

 <Desc / Clms Page number 2>

 in the presence of nitrogen, three parts of powdered iron mixed with two parts of lithium nitride, heated to a temperature of 500-600 C.



   The present process is applicable to the preparation of nitrogen compounds for all known commercial uses of such nitrogen compounds.



   It can also find an important application according to the invention, namely for the synthesis of ammonia. It is actually sufficient, at a temperature of 550-600 C, regardless of the pressure, a mixture of nitrogen and hydrogen over iron, which is in contact with lithium nitride (e.g. 3 parts powdered iron in a mixture with 2 parts lithium nitride) , in the presence of an oxide of a substance of the earth metal group, e.g. B. in the presence of 5-10 percent by weight of clay to be painted so that ammonia is formed.



   You can therefore ammonia even at relatively low pressure, eg. B. of the order of magnitude of atmospheric pressure.



   PATENT CLAIMS:
1. A process for the preparation of catalysts for the ammonia synthesis, characterized in that nitrogen is allowed to act on iron or on one or more metals of the iron group which is in contact with one or more nitrogen-containing compounds Lithium, such as lithium nitride or lithium-nitrogen compounds are located.
