摘      要：The 15%(Co-Mn)/TiO2,(Co/Mn=1/6) catalyst was prepared using fusion procedure and studied for the conversion of synthesis gas to C2 ～ 4 *** effects of calcination conditions and operation conditions such as the H 2 / CO molar feed ratio at different temperatures,gas hourly space velocity(GHSV) and total reaction pressure on the catalytic performance of catalyst were *** stability of the catalyst during 150 h at optimal operation conditions(t = 250℃ H2 /CO= 2/1,GHSV=1 500 h-1 and p =0.3 MPa) has been *** is found that this catalyst is high stable for production C2 ～ 4 *** of both precursors and calcined catalysts by powder X-ray diffraction,scanning electron microscopy(SEM),Brunauer-Emmett-Teller(BET) specific surface area measurement and thermal analysis methods such as thermal gravimetric analysis(TGA) and differential scanning calorimetry(DSC) show that the different preparation method influences the catalyst precursor structure and morphology.
