Chemical reaction engineeringDual-type reactorOptimal design2024 Hydrogen Energy Publications LLCThe ammonia production is one of the most essential petrochemical processes. This article focuses on the heart of this process, the ammonia synthesis reactor. First, an industrial fixed bed reactor for ammonia...
Synthesizing ammonia using lower temperatures and pressures could therefore improve its prospects as a chemical means to store and transport energy. Here we report that alkali and alkaline earth metal imides function as nitrogen carriers that mediate ammonia production via a two-step chemical looping ...

In this process there is a detrimental reaction that occurs between hydrazine and chloramine and that appears to be catalyzed by heavy metal ions such as Cu2+. Gelatin is added to this process to scavenge these metal ions and suppress the side reaction. N2...
Because the gasification of biomass yields syngas, which contains both CO and H2, for production of ammonia, the syngas must first be stripped of its CO through the shift reaction (Eq. 9.2). As mentioned earlier, the shift conversion is aided by commercial catalysts, such as iron oxide and...
A process for the synthesis of ammonia is provided in which the ammonia production is optimized by an automatic control; a predetermined relationship between the equilibrium ammonia-concentration and the outlet ammonia-concentration is controlled; stable operation at a temperature near the temperature of...
Ammonia Chemical Properties,Uses,Production Description Ammonia (chemical formula: NH3) is a compound of nitrogen and hydrogen. As a colorless pungent gas, it is highly soluble in water to become the liquid ammonia. It is also one of the most abundant nitrogen-containing compound in the atmospher...
POROUS CRYSTAL COMPRISING AMMONIA BORANE AND A PRODUCTION METHOD THEREFOR United States Patent Application 20120016146 Kind Code: A1 Abstract: Disclosed does a porous crystal comprising ammonia borane in which the ammonia borane is chemically bonded thereto by a chemical reaction while a porous ...

Alternative routes to the Haber–Bosch process are being sought to electrify ammonia synthesis. Nitric oxide can be electrocatalytically converted into ammonia, but the Faradaic efficiencies and rates of production are currently far below those needed fo
