Abstract: The invention regards a method for electrochemical ammonia synthesis, comprising the steps of: providing at least one electrolysis cell; contacting the cathode with a source of lithium cations, nitrogen, and protons; and subjecting the cathode to a continuous pulsed cathode potential, including a pulsed cathodic current load, wherein the cathode potential is pulsed between the lithium reduction potential and a less negative cathode potential, whereby ammonia is synthesized.

Abstract: Disclosed is a method for the selective catalytic reduction of NOx in waste/exhaust gas by using ammonia provides by heating one or more salts of formula Ma(NH3)nXz, wherein M represents one or more cations selected from alkaline earth metals and transition metals, X represents one or more anions, a represents the number of cations per salt molecule, z represents the number of anions per salt molecule, and n is a number of from 2 to 12, the one or more salts having been compressed to a bulk density above 70% of the skeleton density before use thereof.

Abstract: A method of storing and delivering ammonia and the use of electromagnetic radiation for desorption of ammonia from a chemical complex. Solid metal ammine complexes are applied for safe and high-density storage of ammonia to be released for use as reducing agent in selective catalytic reduction of NOx in exhaust gases. The compositional formula of the metal ammine complexes is M(NH3)nXz, where M2+ represents one or more metal ions capable of binding ammonia, X represents one or more anions, n is the coordination number (from 2 to 12), and z the valency of the metal ion (and thus the total number of compensating anion charges). Ammonia is released non-thermally by photon-activation using electromagnetic irradiation of the complex bond between ammonia coordinated to the metal ion.

The catalyst has a high selectivity and is based an easily available metal compounds.

Abstract: Solid metal ammine complexes are applied for safe and high-density storage of ammonia to be released for use as reducing agent in selective catalytic reduction of NOx in exhaust gases. The compositional formula of the metal ammine complexes is M(NH3)nXz, where MZ+ represents one or more metal ions capable of binding ammonia, X represents one or more anions, n is the coordination number (from 2 to 12), and z the valency of the metal ion (and thus the total number of compensating anion charges). Ammonia is released by generating a reduced gas-phase pressure of ammonia inside the container, which is below the equilibrium desorption pressure of ammonia at the operating temperature of the storage material thus enabling the unit to be operated is a safe manner with lower operating temperature and pressure.
