摘要：

In this study, sulfated zirconia with loading of platinum (Pt) and platinum alumina (PA-Al2O3) promoted sulfated zirconia (SZ) catalysts were synthesized by hydro-thermal route. The samples were characterized by XRD, BET, FT-IR, NH3-TPD, and TGA. The catalytic efficiency of all the synthesized catalysts was tested on the isomerization of n-butane. The results indicated that the conversion of n-butane (71.04%), selectivity to i-butane (98.96%), and yield of i-butane (70.30%) is significantly high for PA/SZ sample than that of Pt modified SZ and bare SZ. The results of this study suggest that the SZ modified by Pt/Al2O3 (PA) provided better catalytic performance and higher stability (within 25 h of TOS), when compared with SZ, and Pt-modified SZ.
