| 摘 要： | 研究了酸处理对ｓｅｐｉｏｌｉｔｅ结构的影响及环己烷在Ｐｔ／ｓｅｐ－Ａｌ２Ｏ３催化剂上的脱氢性能。结果表明，酸处理能使Ｓｅｐｉｏｌｉｔｅ骨架中的呐“发生解离，生成一种高比表面积的产物。环己烷在经酸处理的ｓｅｐｉｏｌｉｔｅ担载Ｐｔ催化剂上的脱氢活性远较Ｐｄ／Ａｌ２Ｏ３高。研究结果还表明，在Ｐｔ／ｓｅｐ－Ａｌ２Ｏ３催化剂上，电子效应较几何效应对环己烷脱氢作用更显著。

| Abstract: | The effects of acid treatment on the structure of sepiolite material and the properties of Pt/sep-Al2O3 catalyst in dehydrogenation of cyclohexane were investigated. The results showed that acid treatment results in the dissolution of magnesium from sepiolite framework and the formation of a high specific surface area material. The catalytic performance determination showed that comparing with Pt/Al2O3, Pt/sep-Al2O3 has higher activity for cyclohexane dehydrogenation and anti-poisoning ability, In addition, the results revealed that electronic effect is more significant than steric effect in cyclohexane dehydrogenation reaction over Pt/sep-Al2O3 catalyst. |
