Ficher-Tropsch synthesis (FTS) is a promising technology of natural gas conversion to syncrude. The main FTS problem is scaling of laboratory reactor up to industrial size. Direct scale up is complicated due to coupling of Fischer-Tropsch reactor chemical kinetics with heat and mass transfer limitations in catalyst pellet and catalytic bed as a whole. Mistakes in reactor design may lead to great overheating in catalytic bed and subsequent catalyst deactivation. High precision mathematical model may be an appropriate way to avoid high costs and mistakes in designing scaled-up FTS reactors. In this study the results of simulation by means of the mathematical model of granulated cobalt catalyst in fixed-bed Fischer-Tropsch reactor are verified with experimental ones obtained from laboratory and scaled-up reactor. It has been shown that for gas hour space velocities over 2400 h-1 the results of simulation (CO conversion, liquid hydrocarbon productivity) are in a good agreement with experimental data. The results of this work show that this mathematical model is suitable for scaling-up fixed-bed Fischer-Tropsch reactors.
