MOSSBAUER SPECTROSCOPY STUDIES OF IRON CATALYSTS USED IN SLURRY PHASE FISCHER-TROPSCH SYNTHESIS
Iron and cobalt are the two principal choices as catalysts for Fischer-Tropsch (F-T) synthesis. As discussed in a recent review by Wender each metal has certain advantages and disadvantages. Davis and co-workers have recently discussed the advantages of iron-based F-T catalysts in some detail. In order to understand the catalytic reaction mechanisms of iron during F-T synthesis, it is critical to identify the active catalytic phases. Moreover, from a practical point of view, it is equally important to identify the reactions and transformations that deactivate the catalysts. {sup 57}Fe Moessbauer spectroscopy is perhaps the best technique available for quantitative characterization of the iron phases in complex samples. For the past several years, our group has been using Moessbauer spectroscopy to characterize the iron-based catalysts prepared and tested for F-T synthesis in a number of DOE-sponsored programs. The results of this investigation have been summarized in detail in DOE reports and in a number of publications released over the past few years. A list of the principal publications resulting from this work is given. A brief summary of the highlights of the results presented in these papers is presented in the current report.
