A bifunctional Co modified Fe3O4-Mn catalyst was prepared for Fischer-Tropsch synthesis (FTS). The influence of Co loading on the synergistic effect of Fe-Co as well as FTS performance over Fe1CoxMn1 catalysts was studied. Incorporation of Co species into the Fe3O4-Mn catalyst promoted the reduction of iron oxides, increasing iron active sites during FTS. Moreover, the adding of Co species enhanced the electron transfer from Fe to Co metal, which strengthened the synergistic effect of Fe-Co, improving the catalytic performance. The Fe1CoxMn1 catalyst with higher Co loading promoted further the hydrogenation ability, favoring the shifting of the product distribution towards shorter hydrocarbons. Under optimized conditions of 280 °C, 2.0 MPa and 3000 h−1, the highest yield of liquid fuels was obtained for the Fe1Co1Mn1 catalyst.A bifunctional Co modified Fe3O4-Mn catalyst was prepared for Fischer-Tropsch synthesis (FTS).
