Chemical Looping Steam Methane Reforming via Ni-ferrite Supported on Cerium and Zirconium Oxides
Pure hydrogen was produced by means of chemical looping steam methane reforming with novel oxygen carriers. Ni-ferrite, Ni-ferrite-ZrO2, and Ni-ferrite-CeO(2)were synthesized as oxygen carriers and characterized by X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) method, scanning electron microscopy (SEM), dynamic light scattering (DLS), and hydrogen temperature-programmed reduction (H-2-TPR). The performances of the as-synthesized oxygen carriers in the cyclic oxidation-reduction were investigated in the packed-bed microreactor at a defined temperature range and under atmospheric pressure. Ni0.39Fe2.61O4-ZrO(2)exhibited the best performance and maximum methane conversion among the other oxygen carriers. In addition, high selectivities for H(2)and CO were reached.
