| مستخلص: | Syngas production from the partial oxidation of (bio)ethanol (POE) was demonstrated. For this purpose, Pt or Ni with different metal loading supported on CeSiOxwere used as catalysts. The catalytic performance was studied in the 600–800 °C temperature range and with oxygen-to-ethanol molar ratios of 0.5 and 0.75. The highest ethanol conversion and H2and CO selectivities were achieved at 800 °C. As byproducts, small amounts of CH4, C2H4O, and C2H4were found, and their selectivity decreased with increasing the reaction temperature. Carbon formation during POE at 800 °C on these catalysts followed the order: 1Pt/CeSiOx< 5Ni/CeSiOx< 1Pt5Ni/CeSiOx< 10Ni/CeSiOx< 1Pt10Ni/CeSiOx. Therefore, 1Pt5Ni/CeSiOxpresented the best performance for the POE reaction at 800 °C, with low byproduct formation and carbon deposition, thus evidencing the cooperative effect of the support and the synergic effect between the Pt and Ni particles. |
