Abstract: The ZrO2 support modified by Y3+, Ce4+, or Al3+ improved the resistance of the Pd-based catalysts to sulphur poisoning. The modification of Pd/ZrO2 with Y3+ or Al3+ led to more active than that of Pd/ZrO2 itself.

Key words: palladium, zirconia, supported catalyst, lean-burn natural gas, methane conversion, sulphur poisoning
