Performances of Fe3O4-FeO Based Fused Iron Catalysts for Fischer-Tropsch Synthesis
Abstract: The effects of reaction temperature, pressure, space velocity, H2/CO ratio and particle size on per-formances of Fe3O4-FeO based fused iron catalysts for Fischer-Tropsch synthesis have been inves-tigated in a fixed-bed reactor. The results show that, the activity of the catalysts was well at low temperature. Conversion of carbon monoxide was 51.93% at 493 K. The selectivity of methane could be decreased by lowering the H2/CO ratio, temperature or space velocity, or increasing the pressure. Especially, the selectivity of methane was decreased from 5.80% to 2.99% by reducing temperature. The inner diffusion was eliminated when the particle size was less than 0.1 mm in the fixed-bed reactor. The effects of reaction conditions on Fe3O4-FeO based fused iron catalysts for Fischer-Tropsch synthesis were found to be similar to the other iron catalysts for Fischer- Tropsch synthesis.
