摘要
Pt/Ce(0.75)Zr(0.25)O(2), Pt/Ce(0.14)Zr(0.86)O(2) and Pt/CeO(2) catalysts proved to be more stable than Pt/Ce(0.50)Zr(0.50)O(2), Pt/CeO(2) (prec), Pt/ZrO(2) and Pt/Al(2)O(3) catalysts on the autothermal reforming of methane under low S/C ratio (0.2). The results showed that the good stability of the Pt/Ce(0.75)Zr(0.25)O(2), Pt/Ce(0.14)Zr(0.86)O(2) and Pt/CeO(2) catalysts is related to a proper amount of oxygen available per metal-support interfacial area on these materials. The high reducibility and oxygen storage/release capacity of support promotes the mechanism of continuous removal of carbonaceous deposits from the active sites, which takes place at the metal-support interfacial perimeter.
