Iron-manganese catalysts were prepared by co-precipitation method. Characterization of catalysts was carried out by using x-ray diffraction (XRD), scanning electron microscopy (SEM), temperature program reduction (TPR), N2 adsorption-desorption measurements. The results from catalytic performance tests in Fischer-Tropsch synthesis showed that the iron-manganese catalysts are supersensitive to catalyst composition and materials source. It was found that C2–4 light olefins increased while CH4 and CO2 decreased by using iron-manganese catalyst prepared from iron (II) sulfate (A catalyst). The activity and selectivity of A catalyst was studied in different operational conditions. The results showed that the best operational conditions for C2–4 light olefins production were H2/CO=1/1 (GHSV=2400 h−1) at 260°C under 0.3 MPa total pressure
