The development of tar dry reforming catalyst systems with superior catalytic performance was essential to address how biomass could be efficiently converted energy. Therefore, a series xY–15Fe–10Ni/Al2O3 (x = 0, 1, 3, and 5) catalysts great activity were prepared by the impregnation method for model compound (xylene) syngas at low temperature (550 °C) in this study. incorporation Y (Yttrium) promoted interaction Ni, Fe support γ-Al2O3 while reducing size nanoparticles (AlNi3, FeAl2O4, etc.) on surface. 3Y–15Fe–10Ni/Al2O3 offered smallest nanoparticle (16.78 nm) strongest interactions so that it strikingly displayed best reaction, conversions xylene CO2 reached 99.94% 67.35%, respectively. Additionally, addition increased dispersion suppressed formation amorphous carbon. deposited carbon active even more abundant form filamentary carbon, which surface accounted 48.43% total are noteworthy as high-performance system or mixed compounds produce synthesis gas. This significance arises from existence alloy spinel structure small particle sizes their surfaces, attached importance.
