Abstract
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 adsorptiondesorption 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=2 400 h-1) at 260 ℃ under 0.3 MPa total pressure.关键词
