Chemical Characterization of a Fused Iron Catalyst for Ammonia Synthesis

Zieliński J., Znak L., Kowalczyk Z.

Polish Journal of Chemistry

2001

Vol. 75, nr 12

1927-1933

A triply promoted fused iron catalyst was examined by (i) temperature-programmed desorption of hydrogen, (ii) temperature-programmed desorption of nitrogen, (iii) temperature-programmed hydrogenation of preadsorbed nitrogen and (iv) chemisorption of carbon monoxide. The studies demonstrate that all the methods arę suitable for characterization of the catalyst, provided that the experimental conditions of the measurements are correctly chosen.
