Disclosed is a method for the selective catalytic reduction of NOin waste/exhaust gas by using ammonia provides by heating one or more salts of formula M(NH)X, 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.

Solid ammonia storage and delivery material

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 NOin exhaust gases. The compositional formula of the metal ammine complexes is M(NH)X, where Mrepresents 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.

A process for hydrogenation of carbon oxides comprising contacting a gas mixture containing carbon oxides and of hydrogen with a catalyst comprising bimetallic iron-nickel or iron-cobalt alloys as the active catalytic material supported on a carrier of an oxide. The carrier is preferably formed to have a surface area greater than 20 m/g.
