Description

Patentiert im Deutschen Reiche vom 6. September 1911 ab. Längste Dauer: 11. Februar 1926.Patented in the German Empire on September 6, 1911. Longest duration: February 11, 1926.

Im Patent 254571 ist ein Verfahren zum Arbeiten mit Wasserstoff oder wasserstoffhaltigen Gasen, insbesondere für die Herstellung von Ammoniak aus den Elementen unter Druck bei erhöhter Temperatur und unter Verwendung von Gefäßen, die mit besonderen Verstärkungen versehen sind, beschrieben, wonach man die Wandung des eigentlichen (innen liegenden) Reaktionsgefäßes aus einem bei den in Betracht kommenden Verhältnissen an sich mechanisch nicht genügend festen, aber gegen Wasserstoff chemisch möglichst widerstandsfähigen Stoff herstellt und dafür sorgt, daß der durch die Gefäßwand hindurchtretende Wasserstoff ohne großen Widerstand entweichen kann.In patent 254571 is a method for working with hydrogen or hydrogen-containing Gases, especially for the production of ammonia from the elements below Pressure at elevated temperature and using vessels made with special Reinforcements are provided, described, after which the wall of the actual (inside) reaction vessel from one with the ratios in question Not mechanically strong enough per se, but chemically as possible against hydrogen Produces resistant material and ensures that the hydrogen passing through the vessel wall without major Resistance can escape.

Es wurde nun gefunden, daß es nicht nötig ist, sich auf die Verwendung von gegen Wasserstoff chemisch widerstandsfähigem Material zu beschränken, daß es vielmehr auch möglich ist, die Wandung des Reaktionsgefäßes aus einem Material herzustellen, welches für Wasserstoff sowohl mehr oder weniger durchlässig, als auch ihm gegenüber chemisch nicht widerstandsfähig ist. Man kann also z. B. für die eigentliche Gefäßwand mehr oder weniger kohlenstoffhaltiges technisches Eisen verwenden. It has now been found that it is not necessary to rely on the use of anti-hydrogen chemically resistant material to limit that it is rather also possible is to produce the wall of the reaction vessel from a material which is suitable for hydrogen both more or less permeable and not chemically resistant to it is. So you can z. B. use more or less carbon-containing technical iron for the actual vessel wall.

Bezüglich der Entlüftung gilt auch hier das im Patent 254571 Gesagte.With regard to venting, what was said in patent 254571 also applies here.

Von besonderer Wichtigkeit ist das Verfahren für die synthetische Darstellung von Ammoniak aus den Elementen unter Druck mit Hilfe von Katalysatoren.Of particular importance is the process for the synthesis of ammonia from the elements under pressure with the help of catalysts.

Abänderung des im Patent 254571 beanspruchten Verfahrens, dadurch gekennzeichnet, daß man die Wandung des eigentliehen (innen liegenden) Reaktionsgefäßes aus einem Stoff herstellt, welcher gegen Wasserstoff chemisch nicht widerstandsfähig ist.Modification of the process claimed in patent 254571, characterized in that that the wall of the actual (inner) reaction vessel made from a substance that is not chemically resistant to hydrogen is.
