| 摘 要： | 本文制备了固体超强酸Pt- S2O82-/ZrO2-Al2O3催化剂，采用XRD、TPR、TG-DTA 、FT-IR等表征手段对催化剂进行了表征，并在高压微反－色谱联合装置上，考察了Pt质量分数和活化温度对催化剂正戊烷异构化性能的影响. 结果表明，Pt能使催化剂的还原温度降低；增强载体表面氢气的溢流效应，提高酸强度；Pt质量分数0.10%、活化温度300℃的催化剂异构化活性最高，在反应温度220℃、压力2.0MPa、氢烃摩尔比4:1、质量空速1.0h-1时，异戊烷产率达62.3%. 在100h内异戊烷收率可稳定在55%左右，选择性在98.0％以上.

| Abstract: | The Pt-S2O82-/ZrO2-Al2O3 solid superacid catalysts were prepared and characterized by XRD,TPR,TG and FTIR.The catalysts were evaluated on a lab-scale high pressure microreactor with online chromatogram unit for n-pentane isomerization as a probe reaction.The effects of the Pt contents and the activation temperatures on the catalyst performance were studied.The results show that Pt can reduce the catalyst reduction temperature.The Pt-S2O82-/ZrO2-Al2O3 catalyst with 0.10% Pt and activation temperature of 300 ... |
