Abstract

H₂-TPR of Pt/CeO₂/Al₂O₃ catalysts was carried out to reveal strong interaction between Pt and support CeO₂/Al₂O₃. The calcination temperature of γ-Al₂O₃, CeO₂/Al₂O₃, Pt/ CeO₂/Al₂O₃, and Pt (or CeO₂) loading were factors influencing reduction behavior of the catalysts. Strong interaction between Pt and CeO₂ facilitated the dispersion of Pt, which led to significant promotion of Pt-catalyzed reduction of CeO₂. It was suggested that obvious synergistic effect among Pt-Ce-Al existed in this optimal catalyst. In steam reforming, it may accelerate the sulfur conversion into H₂S, which is easily to escape and therefore deposition of poisonous sulfur species on the catalyst surface can be greatly avoided.
