MOSSBAUER STUDY OF CO-PRECIPITATED FISCHER-TROPSCH IRON CATALYSTS Academic Article

abstract

• Mssbauer spectroscopy studies of precipitated Fischer-Tropsch (FT) iron catalysts, viz. 100 Fe/5 Cu/4.2 K/x SiO 2 , where x=0,8, 16, 24, 25, 40, or 100, have shown that reduction of the oxide precursor in CO gives rise to -carbide Fe 5 C 2 whose amount decreases with an increase of SiO 2 content. The -carbide is converted into magnetite Fe 3 O 4 while catalyzing the FT synthesis reaction. A correlation between FT activity and the content of -carbide in the catalysts was found, which indicated that -carbide is active for FT synthesis reaction. 1994 J.C. Baltzer AG, Science Publishers.
