A range of 5% Fe/5% Co bimetallic catalysts supported on TiO2 was promoted with 0.1%, 0.5% and 1.0% potassium, chromium and manganese respectively, and their physical properties and Fischer-Tropsch (FT) CO hydrogenation capabilities were evaluated. Low level promotion (0.1% and 0.5%) by K and Cr modestly improved the activity, decreased the selectivity to methane and increased the +C-5 fraction of the FT product while the Mn promoted catalysts retarded activity and reduced selectivity.
