Beschreibung
Zusammenfassung:	The present invention provides a modified zirconia catalyst including zirconia, sulfate anion, a first metal component and a second metal component, wherein the first metal component can contain aluminum or gallium, and the second metal component includes platinum or palladinum. The weight percentage of sulfur atoms of the sulfate anion based on the weight of the modified zirconia catalyst is less than 1.0 wt %. Decreasing the sulfate content of the modified zirconia catalyst during impregnation can remarkably enhance the iso-C7 selectivity and adding alumina into the modified zirconia catalyst can maintain the catalytic activity thereof. The present invention also provides a manufacturing method of the modified zirconia catalyst described above.
