Abstract
CO 2 reforming and partial oxidation of methane were carried out using Pt/Al 2O 3, Pt/ZrO 2, and Pt/10%ZrO 2/Al 2O 3 catalysts, in the temperature range 450–900 °C. The Pt/10%ZrO 2/Al 2O 3 was found to be the most active and stable catalyst for combined CO 2 reforming and partial oxidation of methane. The addition of O 2 to the feed increases CH 4 conversion and the catalyst stability. The deactivation is primarily due to coke formation, which was characterized by thermogravimetric analysis and transmission electron microscopy. The reduction of carbon deposition over zirconia-alumina catalyst is related to Pt-Zr n+ interactions and the high oxygen mobility on zirconia.
