A Comparison of the Distribution of Promoters in Reduced and Oxidized Form of Iron Catalyst in Reduced and Oxidized Form of Iron Catalyst for Ammonia Synthesis

Lendzion-Bieluń Z.

433-440

The distribution of promoters in the reduced form of iron catalyst for the ammonia synthesis was studied using the selective etching method and the electron microscopy technique with EDX analyzer. During the reduction process, calcium and aluminium incorporated into amagnetite particle, do not migrate but they form the CaOźAl2O3 phase. It was found that approximately 30% of the total amount of aluminium is separated in the Al2O3 form.
