ABSTRACT:

The objective of this project is to carry out a Moessbauer spectroscopy study of Iron-based catalysts to identify iron phases present andcorrelate with water gas shift and FT activities. A total of 15 catalysts were evaluated so far. Results are presented on the amounts in each catalyst of the following phases: superparamagnetic phase, hematite ((alpha)-Fe(sub 2)O(sub 3)), magnetite (Fe(sub 3)O(sub 4)), Chi-carbide phase ((chi)-Fe(sub 5)C(sub 2)), and an epsilon-carbide phase ((var epsilon)-Fe(sub 2.2)C).
