Abstract

Liquid hydrogen is produced by electrolysis, under pressure, of water, followed by adiabatic expansion to liquefy the hydrogen. The two processes are combined into a single process. Process is used for production of liquid hydrogen, esp. for use as an energy carrier (fuel). No additional energy is required for the process other than that required for decomposing the water to produce the hydrogen.

Description

Beschreibung zu meiner Patentanmeldung:Description of my patent application:

Flüßigwasserstoffgewinnung durch Elektrolyse.Production of liquid hydrogen by electrolysis.

Anwendungsgebiet: Die Erfindung betrifft die Herstellung flüßigen Wasserstoffes durch die Zusammenlegung der beiden Verfahrensweisen: Wasserelektrolyse und adiabatischer oder ähnlicher Expansion mit dem Ziel flüßigen Wasserstoff herzustellen.Field of application: The invention relates to the production of liquids Hydrogen by combining the two processes: water electrolysis and adiabatic or similar expansion with the aim of producing liquid hydrogen.

Zweck: Flüßiger Wasserstoff wird als Energieträger in immer größeren Mengen gebraucht. Dieses Verfahren soll dazu beitragen diesen billig herzustellen und so eine breitere Anwendung zu ermöglichen.Purpose: Liquid hydrogen is used as an energy carrier in ever larger Quantities needed. This process should help to manufacture it cheaply and thus to enable a wider application.

Es ist bekannt nach D.R.P. 600583 und dem Buch: Die technische Elektrolyse der Nichtmetalle, Springer Verlag Berlin 1954, daß sich Wasser auch unter Druck in seine Bestandteile zerlegen läßt. Außerdem ist hinreichend bekannt, das Gase durch arbeitsleistende Entspannung und adiabatischer Entspannung so niedrige Temperaturen erreichen, daß eine Verflüßigung derselben eintritt, vorrausgesetzt die Anfangstemperatur und der Druck wurden entsprechend eingestellt.It is known according to D.R.P. 600583 and the book: The technical electrolysis der nichtmetalle, Springer Verlag Berlin 1954, that water is also under pressure can be broken down into its components. It is also well known that gases through work-performing relaxation and adiabatic relaxation such low temperatures achieve that a liquefaction of the same occurs, provided the initial temperature and the pressure were adjusted accordingly.

Bisher wurde nicht beachtet, daß beide Verfahren als Einheit gesehen eine hohe Einsparung an Energie mit sich bringt.So far it has not been considered that both procedures are seen as a unit brings a high saving of energy with it.

Denn es muß ausser der Zersetzungsenergie keine weitere Energie aufgewendet werden.Because apart from the decomposition energy, no further energy has to be used will.

Die Verflüßigung des Wasserstoffes kann erreicht werden unter Beachtung der bekannten Verfahrensweisen, indem der Druck im Elektrolyseur so hoch gewählb wird, dass durch entspannen des entstehenden gasförmigen Sauerstoffes der-entstehende gasförmige Wasserstoff in einen Zustand gebracht wird, von dem an durch weiteres Entspannen des Wasserstoffes dieser den flüßigen Zustand erreicht.The liquefaction of the hydrogen can be achieved under consideration the known procedures, in that the pressure in the electrolyzer is so high gewählb is that by relaxing the gaseous oxygen that is created, the one that is created gaseous hydrogen is brought into a state from which on by further Relaxation of the hydrogen this reaches the liquid state.

Der Vorteil der Erfindung ist vor allem, daß ähnlich im Dampfmaschinenprozeß, jedoch nicht als Kreisprozeß, die beiden verschiedenen Aggregatzustände flüßig und gasförmigtdie beiden Gase im für den jeweiligen Arbeitsprozeß günstigsten Aggregatzustand benutzt werden. D.h. als Wasser im flüßigen Zustand der Verbindung Wasserstoff - Sauerstoff auf hohen entsprechenden Druck gebracht werden und als Gase nach der Trennung der Verbindung so entspannt werden, daß der Sauerstoff der ebenfalls entsteht,entspannt wird im gasförmigen Zustand ebenso wie der Wasserstoff im gasförmigen Zustand so daß der letztere verflüßigt wird.The main advantage of the invention is that, similarly in the steam engine process, but not as a cycle process, the two different states of aggregation liquid and gaseous, the two gases are used in the most favorable aggregate state for the respective work process. That means that as water in the liquid state of the connection hydrogen - oxygen are brought to a high corresponding pressure and as gases are so relaxed after the separation of the connection that the oxygen which is also formed is relaxed in the gaseous state just like the hydrogen in the gaseous state so that the latter is liquefied.

Das Energiegefälle welches durch die Entspannung des Sauerstoffes zum Wasserstoff entsteht wird ausgenutzt um dem Wasserstoff saviel Energie zu entnehmen, dass durch intspannen des gasförmigen Wasserstoffes dieser verflüßigt wird.The energy gradient caused by the relaxation of the oxygen to produce hydrogen is used to extract less energy from the hydrogen, that by expanding the gaseous hydrogen it is liquefied.

Der Sauerstoff hat sich nach diesem Prozeß entspannt, abgekühlt und wieder angewärmt. Der Wasserstoff entspannt und verflüßigt.After this process, the oxygen has relaxed, cooled and warmed up again. The hydrogen relaxes and liquefies.

Der Patentanspruch: Die Verbindung der beiden Verfahrensweisen mit dem Ziel der Verflüßigung des Wasserstoffes.The claim: The combination of the two procedures with the goal of liquefying the hydrogen.

Das heißt: Die Druckelektrolyse zum Zweck der späteren Verflüßigung des Wasserstoffes bei entsprechendem Druck durchzufuhren, den Prozeß oder die Verfahrensweise als eine Einheit anzusehen.That means: the pressure electrolysis for the purpose of the later liquefaction to carry out the process or procedure of the hydrogen at the appropriate pressure to be regarded as a unit.
