标题:Electrochemical synthesis of ammonia
发明人：DENVIR ADRIAN; MURPHY OLIVER J; CISAR ALAN; ROBERTSON PRISCILLA; USELTON KYLE
摘要:A method for electrochemical synthesis of ammonia gas comprising providing an electrolyte between an anode and a cathode, providing hydrogen gas to the anode, oxidizing negatively charged nitrogen-containing species present in the electrolyte at the anode to form an adsorbed nitrogen species, and reacting the hydrogen with the adsorbed nitrogen species to form ammonia. Preferably, the hydrogen gas is provided to the anode by passing the hydrogen gas through a porous anode substrate. It is also preferred to produce the negatively charged nitrogen-containing species in the electrolyte by reducing nitrogen gas at the cathode. However, the negatively charged nitrogen-containing species may also be provided by supplying a nitrogen-containing salt, such as lithium nitride, into the molten salt electrolyte mixture in a sufficient amount to provide some or all of the nitrogen consumed in the production of ammonia.

摘要:A method for catalytic synthesis of ammonia under normal pressures, including: performing a reaction of hydrogen and nitrogen to synthesize ammonia under normal pressures by taking a liquid alloy as a catalyst in a reactor, where the reactor contains a molten salt, the density of the molten salt is smaller than that of the liquid alloy, and the molten salt is used for providing a reaction interface and isolating the liquid alloy from being introduced impurities. The first metal reacts with the nitrogen to produce the metal nitride, and the molten salt provides a new reaction interface for the metal nitride to react with the hydrogen to synthesize ammonia, so that ammonia is produced continuously. In addition, the molten salt prevents the liquid alloy from contacting with the oxygen and the water vapor, which prevents the liquid alloy from being oxidized, thus prolonging its service life.

摘要:A method for the anodic electrochemical synthesis of ammonia gas. The method comprises providing an electrolyte between an anode and a cathode, providing nitrogen and hydrogen gases to the cathode, oxidizing negatively charged nitrogen-containing species and negatively charged hydrogen-containing species present in the electrolyte at the anode to form adsorbed nitrogen species and adsorbed hydrogen species, respectively, and reacting the adsorbed nitrogen species with the adsorbed hydrogen species to form ammonia. Nitrogen and hydrogen gases may be provided through a porous cathode substrate. The negatively charged nitrogen-containing species in the electrolyte may be produced by reducing nitrogen gas at the cathode and/or by supplying a nitrogen-containing salt, such as lithium nitride, into the molten salt electrolyte. Similarly, the negatively charged hydrogen-containing species in the electrolyte may be produced by reducing hydrogen gas at the cathode and/or by supplying a hydrogen-containing salt, such as lithium hydride, into the molten salt electrolyte.
