Highly active and stable Pt-SO2-4 /ZrO2-Al2O3 solid superacid catalysts were prepared by simultaneously introducing appropriate amounts of Pt and Al2O3 into a SO2-4 /ZrO2 catalyst. The effect of Al content on the performance of the catalysts was studied using n-pentane isomerization as a probe reaction and the catalysts were characterized by X-ray diffraction (XRD), specific surface area measurements (BET), infrared (IR) spectroscopy, temperature-programmed reduction (TPR), thermogravimetry-differential thermal analysis (TG-DTA), and NH3 temperature-programmed desorption (NH3-TPD). The results show that Al can increase the crystallization temperature of ZrO2 and inhibit the decomposition of sulfur. Al can also increase the surface area of the catalyst, strengthen the combination between S and O, improve the redox performance of the catalyst and increase the acid strength and the acidity of the catalyst. The catalytic activity of the Pt-SO2-4 /ZrO2-Al2O3 solid superacid catalyst with a Al2O3 mass fraction of 5.0% was found to be the best. The isopentane yield was stable above 52.0% and the selectivity was higher than 98.2% within 100 h.
