Kinetic and Product Distribution Modeling of Fischer-Tropsch Synthesis in a Fluidized Bed Reactor

A mathematical model for the Fischer-Tropsch synthesis in a fluidized bed reactor was developed. A comprehensive kinetic model was applied for modeling of a fluidized bed reactor so that the CO conversion was correlated with good accuracy over the range of the reactor conditions of 523-563K, 0.95-2.55MPa and H2/CO ratio 0.65-1.51. Using the comprehensive kinetic model, the results of CO conversion in a fluidized bed reactor showed a very good agreement with the experiment. The results of modeling showed that the Average Absolute Deviation percentage (AAD %) of 8.98% for CO conversion. In addition, a proper product distribution model for FT process using the appropriate kinetic model has been developed. The results revealed only 8.09% deviation from the olefin experimental data and 10.27% deviation from the paraffin experimental data that is acceptable in comparison with previous literatures.
