Abstract

A method for energy generation by production of aluminium nitride and reaction thereof with water to give aluminium oxide and ammonia is disclosed.

Description

Die vorliegende Erfindung betrifft ein Verfahren zur Ener­ gieerzeugung.The present invention relates to a method for energy gieerzeugung.

Erfindungsgemäß soll ein Verfahren zur Energieerzeugung zur Verfügung gestellt werden, bei dem auf auf der Erde in großem Umfang vorhandene Ressourcen zurückgegriffen werden kann.According to the invention, a method for generating energy is said to Be made available to those on Earth in existing resources can be used to a large extent can.

Diese Aufgabe wird erfindungsgemäß durch ein Verfahren zur Energieerzeugung durch Erzeugung von Aluminiumnitrid (AlN) und Umsetzung desselben mit Wasser zu Aluminiumoxid (Al2O3) und Ammoniak (NH3) gelöst.This object is achieved according to the invention by a method for generating energy by producing aluminum nitride (AlN) and reacting the same with water to give aluminum oxide (Al 2 O 3 ) and ammonia (NH 3 ).

Die bei der Erzeugung von Aluminiumnitrid und/oder bei Um­ setzung desselben mit Wasser zu Aluminiumoxid erzeugte thermische Energie wird erfindungsgemäß genutzt, beispiels­ weise zur Umwandlung der thermischen Energie in Bewegungs­ energie. So wird das in der Form von Feststoffpartikeln in einem heißen Gasstrom anfallende Aluminiumnitrid beispiels­ weise zum Betreiben von Turbinen eingesetzt, wobei die Alu­ miniumnitriderzeugung entweder direkt in einer Turbinen­ kammer oder in einer Reaktionskammer erfolgt, von der aus der die Aluminiumnitridpartikel enthaltende heiße Gasstrom einer Turbine zugeführt wird. The in the production of aluminum nitride and / or in order setting it with water to alumina Thermal energy is used according to the invention, for example way to convert thermal energy into motion energy. So this is in the form of solid particles in a hot gas stream resulting aluminum nitride for example used to operate turbines, the Alu minium nitride generation either directly in a turbine chamber or in a reaction chamber from which the hot gas stream containing the aluminum nitride particles is fed to a turbine.  

Ferner oder statt dessen wird die bei der Umsetzung des er­ zeugten Aluminiumnitrides mit Wasser zu Aluminiumoxid und Ammoniak gewonnene Energie erfindungsgemäß genutzt, bei­ spielsweise ebenfalls in Bewegungsenergie umgewandelt, wo­ bei ebenfalls beispielsweise hiermit Turbinen betrieben werden. Die Umsetzung wird ebenfalls direkt in einer Turbi­ nenkammer oder in einer entsprechenden Reaktionskammer durchgeführt.Furthermore, or instead, the implementation of the he produced aluminum nitrides with water to aluminum oxide and Ammonia energy used according to the invention, at for example also converted into kinetic energy where also operated with turbines for example become. The implementation is also done directly in a turbo chamber or in a corresponding reaction chamber carried out.

Des weiteren sieht das erfindungsgemäße Verfahren vor, daß der erzeugte Ammoniak als Energieträger für Wasserstoff verwendet wird, d. h. zusätzlich oder anstelle der vorste­ hend beschriebenen Energiegewinnungsstufen wird der er­ zeugte Ammoniak in Stickstoff und Wasserstoff gespalten, wobei durch Verbrennung des Wasserstoffes (beispielsweise in einer Brennstoffzelle) eine weitere Energiegewinnungs­ stufe initiiert wird.Furthermore, the method according to the invention provides that the ammonia generated as an energy source for hydrogen is used, d. H. in addition to or instead of the previous one The energy generation stages described will be the produced ammonia split into nitrogen and hydrogen, by burning the hydrogen (for example in a fuel cell) another energy generation stage is initiated.

Was die Erzeugung des Aluminiumnitrides betrifft, so sieht die Erfindung vor, daß gemäß einer ersten Ausführungsform Aluminiumnitrid durch Reaktion von Aluminium mit Stickstoff erzeugt wird. Diese Reaktion läuft nach der Gleichung
As far as the production of aluminum nitride is concerned, the invention provides that, according to a first embodiment, aluminum nitride is produced by the reaction of aluminum with nitrogen. This reaction follows the equation

2Al + N2 → 2AlN
2Al + N 2 → 2AlN

ab. Das gewonnene Aluminiumnitrid wird dann in einer weite­ ren Stufe mit Wasser zu Aluminiumoxid und Ammoniak umge­ setzt. Das für dieses Verfahren benötigte Aluminium wird beispielsweise durch Reduktion aus Aluminiumoxid (Al2O3) gewonnen.from. The aluminum nitride obtained is then converted in a further step with water to aluminum oxide and ammonia. The aluminum required for this process is obtained, for example, by reduction from aluminum oxide (Al 2 O 3 ).

Bei einer anderen Variante zur Erzeugung des Aluminium­ nitrides wird Aluminiumoxid direkt mit Kohlenstoff und Stickstoff umgesetzt, so daß sich Aluminiumnitrid ergibt. In another variant for producing the aluminum nitrides will directly with carbon and aluminum oxide Nitrogen reacted so that aluminum nitride results.  

Diese Reaktion läuft nach der folgenden Gleichung ab:
This reaction follows the following equation:

Al2O3 + 3C + N2 → 2AlN + 3COAl 2 O 3 + 3C + N 2 → 2AlN + 3CO

In der zweiten Stufe des erfindungsgemäßen Verfahrens er­ folgt die Umsetzung des Aluminiumnitrides mit Wasser zu Aluminiumoxid und Ammoniak. Das gewonnene Aluminiumoxid kann wieder als Ausgangsprodukt für die Herstellung von Aluminium bzw. Aluminiumnitrid eingesetzt werden. Der ge­ wonnene Ammoniak kann als solcher verwendet werden (Dünge­ mittel etc.) oder als Energieträger für Wasserstoff dienen, wie vorstehend erwähnt. Bei dem erfindungsgemäßen Verfahren kann somit auf das in großem Umfang auf der Erde vorhandene Aluminiumoxid als Ausgangsprodukt zurückgegriffen werden, aus dem in einer ersten Stufe Aluminiumnitrid und letztend­ lich in einer zweiten Stufe Ammoniak hergestellt wird. Die in den einzelnen Reaktionsstufen erzeugte Energie wird ge­ nutzt, beispielsweise in Bewegungsenergie umgewandelt, und/ oder die im Endprodukt Ammoniak enthaltene Energie wird ge­ nutzt (durch Wasserstofferzeugung und Wasserstoffverbren­ nung). Das erfindungsgemäße Verfahren stellt daher in bezug auf die Energieerzeugung eine Alternative zu den bestehen­ den Energieerzeungsverfahren auf der Basis von Kohlenstoff bzw. Kohlenwasserstoffen dar.In the second stage of the method according to the invention the reaction of the aluminum nitride with water follows Alumina and ammonia. The aluminum oxide obtained can again be used as the starting product for the production of Aluminum or aluminum nitride can be used. The ge Recovered ammonia can be used as such (fertilizer medium etc.) or serve as an energy source for hydrogen, as mentioned above. In the method according to the invention can thus be based on what exists on earth on a large scale Aluminum oxide can be used as a starting product, from the aluminum nitride in a first stage and finally ammonia is produced in a second stage. The Energy generated in the individual reaction stages is ge uses, for example converted into kinetic energy, and / or the energy contained in the final product ammonia is ge uses (through hydrogen production and hydrogen burning voltage). The method according to the invention therefore relates an alternative to the insist on energy production the energy generation process based on carbon or hydrocarbons.
