Fischer‐Tropsch synthesis (FTS) on K promoted Fe catalyst was studied in three bubble column slurry reactors (BCSR) of 2.5, 5, and 10 cm diameter. The objective was to check data reproducibility under conditions of arbitrary alterations of various parameters. First order rate constants evaluated on the basis of appropriate slurry reactor models were chosen as an approximate measure to characterize data reproducibility and catalyst activity. It was found that rate constants and hence reproducibility may differ by a factor of two if different batches and precipitations of catalyst are considered. Within the parameter ranges covered in this study this rule of thumb is valid irrespective of reactor diameter, type of sparger, catalyst concentration, temperature, pressure, and gas flow rate. The rate constants compare well with literature data.
