KCC Seminar: Difference between iron and ruthenium catalysts for ammonia synthesis

May 15 2017 10:00 AM - May 15 2017 11:30 AM


Ammonia synthesis is one of the most established and mature chemistries in heterogeneous catalysis from both academic and industrial point of views. Ammonia is one of the CO2 free hydrogen carriers and can be used as the direct fuels. The presentation describes how ammonia is important in current society, how the catalyst has been established in the history, and reaction mechanisms have been investigated and discussed in the laboratory scale and translated into industrial scale. Iron and ruthenium catalysts are effectively compared and the essential role of promoter is introduced.

The lecture is devoted to late Prof. Atsumu Ozaki
