In situ Mössbauer spectra recorded at 570 and 80 K are reported for Cab-O-Sil supported iron-ruthenium Fischer-Tropsch catalysts with different Ru/Fe ratios. The effect of ruthenium has been revealed in the hinderance of carbide formation and in the improved stability of the catalyst. Spectra obtained in hydrogen and in increased CO/H2 ratio atmospheres are also discussed.
