Abstract
(DE)
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Ammoniak, sowie eine Vorrichtung zur Herstellung von Ammoniak. Sie umfasst eine elektrolytische Herstellung eines Metalls M an einer Kathode einer Elektrolysezelle, wobei M ausgewählt ist aus Li, Mg, Ca, Sr, Ba, Zn, Al, und/oder Legierungen und/oder Mischungen davon, weiter eine Herstellung eines Nitrids des Metalls M durch Umsetzung des elektrolytisch hergestellten Metalls M mit einem Gas umfassend Stickstoff, sowie ein Einbringen des Nitrids des Metalls M in die Elektrolysezelle, bevorzugt in einen Anodenraum der Elektrolysezelle, und eine Umsetzung des Nitrids des Metalls M an einer Anode der Elektrolysezelle zu Ammoniak.
(EN)
The present invention relates to a process for producing ammonia and to an apparatus for producing ammonia. It comprises the electrolytic production of a metal M at a cathode of an electrolysis cell, wherein M is selected from Li, Mg, Ca, Sr, Ba, Zn, Al and/or alloys and/or mixtures thereof, production of a nitride of the metal M by reaction of the electrolytically produced metal M with a gas comprising nitrogen, introduction of the nitride of the metal M into the electrolysis cell, preferably into an anode chamber of the electrolysis cell, and reaction of the nitride of the metal M at an anode of the electrolysis cell to produce ammonia.
