The objective of this study was to develop a kinetic model to describe the selectivity typical of iron-based Fischer-Tropsch catalysts and to compare the simulations of the process in the slurry stirred tank reactors with experimental data. The model accounts for the formation of paraffins and olefins and also for the water-gas shift and secondary hydrogenation of olefins. Non-Schulz-Flory distribution was obtained due to olefin readsorption followed by chain growth. The simulation results show fair agreement with experimental data obtained in a laboratory stirred tank reactor with the use of a commercial iron-based catalyst Ruhrchemie LP 33/81 suspended in the molten octacosane.
