Catalytic reaction performances of home-made mesoporous MnO2-supported Fe-based catalyst with copper promoter for Fischer-Tropsch synthesis (FTS) are investigated in a slurry-phase reactor at 533 K-573 K and 1.0 MPa. The present catalyst system exhibits high olefin selectivity, however, the selectivity to ethylene is lower than the extrapolation based on the C-3(+). Simultaneously, the catalyst gives high oxygenates productivity except for the C-1 oxygenates. Comprehensive product distributions including hydrocarbon and oxygenates at different temperatures are presented. Particular attention is paid to the new overall distribution of product based on the carbon numbers when the hydrocarbon is combined with oxygenates. The new distributions at different temperatures show similar trends, displaying low C-1 product selectivity and almost accordant C-2 product selectivity with the extrapolation from Anderson-Schulz-Flory (ASF) law. An attempt is made to elucidate the deviation behavior of C-1 and C-2 hydrocarbon. (C) 2011 Elsevier Ltd. All rights reserved.
