TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Process: The reaction system is operated at 50-450 degrees C, preferably 150-250 degrees C. The ammonia in gaseous or liquid condition is contacted into the reaction system. At least a promoter is added to the catalyst, where the promoter is preferably salts from metals of the main groups of Ia or IIa, lanthanide and/or actinide. The ammonia flows into the plant in a diluted form into another gas such as nitrogen, helium, argon, or is added in pure form. Preferred Components: The catalyst is metal or an alloy with a metal of the subgroup, which consists of VIIIb or Ib and carbon nanotubes, activated carbon, a metal oxide of the main group IIa, aluminum oxide, zirconium oxide, titanium oxide, silicon oxide, magnesium aluminate or zeolite. The mass fraction of the solid catalyst is 0.5-95%, preferably 5-30%.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The reaction system is a continuously operated decomposition reactor, preferably continuously operated in a bubble column reactor, a fumigated or non-fumigated suspension reactor, a solid bed reactor or a turbulence layer reactor.
