Abstract

In this study, the effect of the addition of Zn to a NiFe₂O ₄ catalyst was investigated for a high-temperature shift (HTS) of the natural gas reformate under the assumption that no external steam was added. In our previous study, NiFe₂O₄ proved to be a notable HTS catalyst, but it produced methane as a by-product in the presence of such a highly reductive reformate. In this study, we found that the addition of Zn to NiFe₂O₄ was effective in suppressing methanation as well as in promoting HTS activity. Such improvements were expected to be related to the enhanced redox property of the inverse-spinel species included in the catalyst. To elucidate the effects of Zn addition, inductively coupled plasma spectroscopy (ICP), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), thermo-gravimetric analysis under a CO gas atmosphere (CO-TGA), and temperature-programmed reduction of H₂ (H₂-TPR) were performed.
