Abstract

The effect of process variables (temperature, pressure, space velocity, and H2/CO feed ratio) on the Fischer‐Tropsch 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 280°C 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 0.64‐0.72 range of H2/CO feed ratios. Spacetime‐yield increases with pressure, and reactor productivity is best increased by increasing pressure at a constant pressure to space velocity ratio. The water‐gas‐shift reaction is near equilibrium at high conversions, and always proceeds at a slower rate than the Fischer‐Tropsch synthesis in a STR.
