Abstract

Pt/CeO₂/Al₂O₃ catalysts with or without Gd₂O₃ modifier were characterized. Gd₂O₃ modifier enhanced the interaction of Pt and CeO₂ between their interface. Gd₂O₃ facilitated the formation of CeAlO₃ phase due to the strengthened reducibility of CeO₂, which in turn suppressed the sintering of both Pt and CeO₂. The Gd₂O₃-modified Pt/CeO₂/Al₂O₃ catalyst exhibited excellent activity and sulfur-tolerant stability for steam reforming of iso-octane blended with 300 μg/g sulfur (thiophene as sulfur source). Throughout the entire 250 hr test, a 100% iso-octane conversion was achieved, with H₂ mole fraction of 73% and CH₄ mole fraction < 1%.
