Resumen:
In this work, a COPrOx monolithic reactor with a CuO/CeO2/Al2O3 catalytic washcoat was modelled to purify a H2 stream for a 2 kW PEM fuel cell. Preliminary simulations included isothermal monoliths operating between 423 and 463 K, and the optimization of linear axial temperature profiles. For a given total system size and a desired CO exit molar fraction lower than 20 ppm, an isothermal temperature profile maximized global selectivity towards CO oxidation. Then, different schemes of adiabatic monoliths with interstage cooling were modelled and evaluated. It was found that wide operating temperature ranges lower the necessary stages number, but decrease global selectivity and rise system sensitivity to inlet temperatures. To model the monoliths, a 1D heterogeneous model was used.
