Abstract
Effects of calcination temperature for Pt-SO 4 2- /ZrO2-Al2O3 (PSZA) catalysts in n-hexane hydroisomerization were investigated by N2-adsorption, XRD, TG-DTA, FTIR, XPS and H2-TPR. An optimum calcination temperature is helpful to complete the crystallization process, resulting in better distribution of alumina into zirconia crystal and producing new acid centers responsible for higher catalytic activity.
