Structure and Surface Chemistry of Industrial Ammonia Synthesis Catalysts... 

This chapter deals with the structure and surface chemistry of industrial ammonia synthesis catalysts. Results on catalyst models and single crystal surfaces are included to the extent that they illuminate the behavior of industrial catalysts. 

The second chapter Structure and Surface Chemistry of Industrial Ammonia Synthesis Catalysts is written by Dr. Per Stoltze. This chapter deals with the structure and surface chemistry of iron-based ammonia synthesis catalysts of the type used by industry. Certain studies of single crystal surfaces are included to the extent that they serve to add information to the main topic. This chapter includes a presentation of the unreduced catalyst the reduction process and the bulk and surface structure of a reduced catalyst. A thorough discussion is given of the different states of sorption of nitrogen and of chemisorption of hydrogen, carbon oxides, ammonia and oxygen. The last part of the chapter gives a detailed account of the mechanism of ammonia synthesis on iron.
