abstract

  • The effect of process variables (temperature, pressure, space velocity, and H2/CO feed ratio) on the FischerTropsch synthesis on a promoted fused iron catalyst was studied in a slurry phase stirred tank reactor (STR). Operating conditions were chosen such that some of the data could be compared with previously reported results, but experiments were also performed at more extreme conditions (temperatures up to 280C and pressures up to 2.86 MPa) than previously studied in a slurry phase STR. The catalyst activity compares well with previous studies at an H2/CO feed ratio of 1.0 and 1.8, but the activity is lower than previously reported values in the 0.640.72 range of H2/CO feed ratios. Spacetimeyield increases with pressure, and reactor productivity is best increased by increasing pressure at a constant pressure to space velocity ratio. The watergasshift reaction is near equilibrium at high conversions, and always proceeds at a slower rate than the FischerTropsch synthesis in a STR.
