Preliminary results on the role of the deposition of small amounts of ZrO2 on Al2O3 support on the partial oxidation of methane and ethane over Rh and Ni supported catalysts

摘要

Alumina supported samples have been prepared by impregnation of the support with a solution of zirconium isopropoxide in n-propanol to obtain after calcination a theoretical monolayer of zirconia (1ZrAl). The formation of a layer of tetragonal zirconia crystals over alumina was observed. Catalysts were evaluated in the partial oxidation of methane (CPOM) and ethane(CPOE) and characterized by elemental chemical analysis, BET specific surface area, X-ray diffraction, X-ray photoelectron spectroscopy and hydrogen chemisorption.
