Ammonia synthesis

Ammonia synthesis catalysts have been based on iron since the first commercial production in 1913. Conventional ammonia synthesis catalysts are made of magnetite (Fe3O4) with structural and electronic promoter. However, Süd-Chemie now is manufacturing an ammonia synthesis catalyst based on non stoichiometric iron oxide, wustite (Fe1-xO) with a cubic crystal structure. This catalyst more active at lower temperature and lower pressure and hence, allows a more efficient ammonia production.

AmoMax-10 is a new ammonia synthesis catalyst developed by Süd-Chemie. It is still iron-based, however, uses a different iron oxide source, wustite. Compared to classic magnetite based ammonia synthesis catalyst, AmoMax-10 exhibits an about 70% higher catalytic activity.
