The Effect of Modifiers on the Performance of Ni/CeO<sub>2</sub> and Ni/La<sub>2</sub>O<sub>3</sub> Catalysts in the Oxy–Steam Reforming of LNG

The Effect of Modifiers on the Performance of Ni/CeO<sub>2</sub> and Ni/La<sub>2</sub>O<sub>3</sub> Catalysts in the Oxy–Steam Reforming of LNG

This work interrogates for the first time the catalytic properties of various monometallic Ni catalysts in the oxy-steam reforming of LNG. Various research techniques, including X-ray diffraction (XRD), specific surface area and porosity analysis (BET method), scanning electron microscopy with X-ray...
