研究了添加Ａｌ对ＳＯ２－４／ＺｒＯ２超强酸样品的晶化、比表面、硫含量、超强酸性和正戊烷反应性能的影响，考察了活化温度、反应温度、Ａｌ含量和载Ｐｔ对催化剂活性和选择性的影响．ＳＯ２－４／Ａｌ２Ｏ３ＺｒＯ２催化剂的酸强度与ＳＯ２－４／ＺｒＯ２基本相当，但超强酸位比后者多，未载Ｐｔ时正戊烷反应活性和稳定性明显高于后者．负载Ｐｔ后，正戊烷异构化选择性和稳定性大大提高，但Ｐｔ／ＳＯ２－４／Ａｌ２Ｏ３ＺｒＯ２催化剂的反应活性与Ｐｔ／ＳＯ２－４／ＺｒＯ２相近，Ａｌ的促进作用不明显 The effects of Al addition on the crystallization, specific surface area, sulfur content, super acidity and n-pentane reactivity of SO2-4 / ZrO2 superacid were studied. The influence of activation temperature, reaction temperature, Al content and Pt loading on the catalyst activity And selective effects. The acid strength of SO2-4 / Al2O3ZrO2 catalyst is almost the same as that of SO2-4 / ZrO2, but the super acidity is higher than that of the latter. The reaction activity and stability of n-pentane without Pt were obviously higher than those of the latter. The selectivity and stability of n-pentane isomerization were greatly improved after loading Pt, but the reactivity of Pt / SO2-4 / Al2O3ZrO2 was similar to that of Pt / SO2-4 / ZrO2, and the promoting effect of Al was not obvious
