Abstract	The new Ce-promoted skeletal Fe catalysts with different Ce contents were prepared through alkali leaching of rapidly quenched ternary FeCeAl alloys and evaluated in the gas-phase Fischer-Tropsch synthesis reaction. N-2 physisorption and XRD analysis confirmed the function of Ce as a structural promoter. In the Fischer-Tropsch synthesis reaction, the incorporation of Ce markedly improved the activity and selectivity to C5+ hydrocarbons. Characterizations of the catalysts after Fischer-Tropsch synthesis confirmed the function of Ce as a chemical promoter. We also confirmed that the catalytic activity is associated with the concentrations of the surface polymeric and, to a lesser extent, atomic carbonaceous species and the C5+ selectivity correlated well with the surface concentration of Hagg carbide. We identified a linear relationship between the concentrations of the Ce-III cations and Hagg carbide, which clearly substantiated the hypothesis that the chemical effect of Ce is mediated by the (FeCeIII)-Ce-0 ensembles facilitating the formation of Hagg carbide.
