Deactivation of Synthesis Catalyst

  • P. E. Højlund Nielsen
Part of the Fundamental and Applied Catalysis book series (FACA)


The catalytic synthesis of ammonia from hydrogen and nitrogen was invented around 1910. Already by that time it had been established that a reduced, promoted magnetite was superior to all other catalysts, except osmium. Since that time, reduced magnetite has continued to provide the basis for ammonia synthesis, even though numerous attempts have been made to make better catalysts.
