Description

Nachstehend ist ein Verfahren beschrieben, welches die katalytische Darstellung von Wasserstoff aus Kohlenoxyd und Wasserdampf in technisch besonders vorteilhafter S Weise ermöglicht.The following is a description of a method which catalyzes the preparation of Enables hydrogen from carbon oxide and water vapor in a technically particularly advantageous manner.

Das Verfahren besteht darin, daß man in das den Kontaktraum verlassende, in der Regel schon zur Vorwärmung der eintretenden Gase verwendete aber noch heiße Gasgemisch kaltes Wasser einführt und das so erhaltene heiße Wasser zur Aufwärmung und Wasserdampfbeladung neuen kalten, dem Kontaktofen zuzuführenden kohlenoxydhaltigen Gases verwendet. Hierdurch wird ein großer Teil des für das Verfahren nötigen Frischdampfes in einfacher Weise geliefert, indem insbesondere die latente -Kondensationswärme des in den abziehenden Gasen noch enthaltenen Wasserdampfes nutzbar gemacht wird.The method consists in that one leaves the contact space in the Usually already used to preheat the incoming gases but still hot gas mixture introduces cold water and the hot water obtained in this way for heating and water vapor loading new cold, the Contact furnace to be supplied carbon oxide-containing gas used. This becomes a large part of the live steam required for the process is supplied in a simple manner, in particular by the latent heat of condensation in the withdrawing gases still contained water vapor is made usable.

Man verfährt dabei z. B. in der Weise, daß man die aus den Kontaktöfen abziehenden Gase in Einspritzkühlern im Gegenstrom mit einer zur Kondensation der Hauptmenge des Wasserdampfes und zur Abkühlung der Gase ausreichenden Kühlwassermenge zusammenbringt und das aus dem Kühler ablaufende Wasser, das die Summe des eingespritzten und kondensierten Wassers darstellt, nun in einem anderen Apparat, dem Verdunster, im Gegenstrom mit dem frischen, noch nicht mit Dampf versetzten Wassergas ο. dgl. zusammenbringt, so daß sich dieses bei der Temperatur des heißen Wassers mit Wasserdampf sättigt. Die Menge des einzuspritzenden Kühlwassers wird zweckmäßig so bemessen, daß die Temperatur des austretenden Wassers möglichst hoch und gleichzeitig diejenige der austretenden Gase möglichst niedrig ist. Wechselnde Betriebsverhältnisse, wechselnde Belastung der Kontaktöfen usw. bedingen also jeweils eine andere Einstellung der Kühlwassermenge.One proceeds z. B. in such a way that one withdraws from the contact furnaces Gases in injection coolers in countercurrent with a condensation of the bulk of the Brings together water vapor and sufficient cooling water to cool the gases and the water draining from the cooler, which is the sum of the injected and condensed water, now in another device, the evaporator, in countercurrent with the fresh one, not yet with Steam added water gas ο. Like. Brings together, so that this is at the temperature of the hot water is saturated with water vapor. The amount to be injected Cooling water is expediently dimensioned so that the temperature of the exiting water as high as possible and at the same time that of the escaping gases is as low as possible. Changing operating conditions, changing loads on the contact furnaces, etc. so a different setting of the cooling water quantity in each case.

Es wurde weiter gefunden, daß es vielfach zweckmäßig ist, die Kondensation und Abkühlung und gegebenenfalls auch die Aufwärmung der Gase in zwei oder mehreren Stufen durchzuführen.It has also been found that it is often expedient to use the condensation and cooling and optionally also the warming up of the gases in two or more To carry out stages.

Mittels des beschriebenen Verfahrens gelingt es leicht, 50 Prozent oder mehr von dem für die Reaktion erforderlichen Wasser als Dampf zu erhalten.Using the method described, it is easy to achieve 50 percent or more of to obtain the water required for the reaction as steam.
