| Hydrogen-syngas production is one of the actual and continuous problem in the petrochemical and refining industry, whereas a process that exhibits an optimal industrial efficiency and usage is needed. The use of mixed metal oxides (FeMO4, FeMoO4, Fe2ZnO4, Fe2MnO4) as oxygen carriers is proposed to minimize the disadvantages of the current partial oxidation of methane. The objective of the present work is to identify oxides that help the production of syn-gas and are able to regenerate through favorable conditions. This is accomplished by simulating an arrangement of two reactors. The main reduction reaction is carried out in the first reactor: CH4 + Fe2MO4 = H2 + CO + Fe + M. While in the second reactor the following reaction is carried out: Fe + M + H2O = Fe2MO4 + H2. Results indicate that It is possible for the oxide to be completely regenerated, while optimal reaction parameters were obtained for each reactor observing that the material were completely regenerated while not affecting the hydrogen. FeMoO4 produced syn-gas at 750 ° C. However, it was possible not regenerate at favorable conditions. Otherwise, Fe2ZnO4 produced syn-gas at 730 ° C and regeneration was feasible at 440 °C. Finally, Fe2MnO4 produced syn-gas at 640 °C with regeneration at 600 °C, being the one with the best operating conditions among the studied materials. Simulation results of the different oxides are presented using Aspen-Plus©. | |
