Perovskites supported on Al2O3 (LaNi/AL) and CeO2-SiO2 (LaNi/CS) were tested as catalyst precursors for steam reforming of liquefied petroleum gas (SRLPG). The role of different supports in perovskites-derived catalysts performances was evaluated. A non-supported LaNiO3 (LaNi) was also synthesized for comparison. According to the in-situ X-Ray Diffraction analyses, a reduction temperature of 700 degrees C was enough to generate Ni-0 and La2O3, except for LaNi/AL. X-ray absorption Near Edge Spectroscopy (XANES) showed a direct influence of the supports on the reducibility of the samples. At 600 degrees C, the supported precursors LaNi/AL and LaNi/CS were more stable than LaNi during the SRLPG reaction. The alumina support provided a higher activity to LaNi/AL mainly due to the strong metal-support interaction. At 700 degrees C, the LPG conversion of LaNi/CS was near 100%. At both temperatures, the lowest carbon accumulation rate was obtained by LaNi/CS likely due to ceria oxygen mobility. (C) 2020 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
