Effects of ZnO content on the performance of Pd/Zr0.5Al0.5O1.75 catalysts used in lean-burn natural gas vehicles

doi:10.1016/S1872-2067(14)60062-0

Abstract

Abstract:

Mixed oxides obtained by adding varying amounts of ZnO into Zr_0.5Al_0.5O_1.75 were used as supports to prepare 1.5% Pd catalysts. The catalyst activity and H₂O tolerances of the catalysts were evaluated in a gas mixture simulating the exhaust of lean-burn natural gas-fueled vehicles. The catalysts were further characterized by N₂ adsorption-desorption, X-ray diffraction, H₂ temperature programmed reduction and X-ray photoelectron spectroscopy. The catalytic activity was greatly influenced by ZnO contents in Zr_0.5Al_0.5O_1.75 support. The catalyst containing 15% ZnO exhibited a light-off temperature and complete conversion temperature for CH₄ in the absence of H₂O of 278 and 314℃, respectively; while these same values in the presence of H₂O were 342 and 371℃, respectively. These results indicate that this combination of materials offers excellent catalytic activity at low temperature and also exhibits significant H₂O tolerance.

Key words: Zirconium, Aluminium, Zinc, Palladium, Mixed oxide, Lean-burn, Natural gas fuelled vehicles, Water inhibition
