| Résumé : | The multiobjective optimization of an industrial autothermal reformer consisting of a noncatalytic partial oxidation (POX) chamber and a two-section catalytic steam reformer was studied in order to produce syngas with H2/CO ratio near 1 for application in Fischer−Tropsch and oxo processes. Both thermodynamic modeling of the POX section and mathematical modeling of fixed beds were used for the optimization of the process for maximizing of methane conversion and CO selectivity and minimizing of CO2 makeup flow. The nonsorting genetic algorithm II was employed for the optimization problem. The adjustable parameters are feed temperature, O2/CH4 ratio, steam to methane (S/C) ratio, and the first and second catalytic bed lengths of the reforming part. The optimized case proposes a syngas product with H2/CO of 1 by a feed including O2/CH4 and S/C of 0.59 and 2.012, respectively. The optimized lengths of two catalytic beds are 1.79 m for the first bed and 5.51 m for the second. |
