In this work, the effect of adding Y2O3 to Rh/a-Al2O3 in the partial oxidation and in the autothermal reforming of methane was investigated. The surface properties of the catalysts were studied using temperature programmed reduction (TPR), X-Ray diffraction, H2 chemisorption and diffuse reflectance infrared spectroscopy (DRIFTS) of adsorbed CO. The addition of ytria improved the catalyst performance both for partial oxidation and autothermal reforming of methane. The Rh/10% Y2O3.a-Al2O3 catalysts presented the best conversion and hydrogen selectivity. This may be explained by the formation of a new active site, with changes in the chemical state of rhodium due to a higher interaction between metal and support.
