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。
The effect of acid treatment on the structure of sepiolite and the dehydrogenation performance of cyclohexane over Pt / sep-Al2O3 catalyst were investigated. The results show that the acid treatment can cause the dissociation of Na in the Sepiolite framework to produce a high surface area product.The dehydrogenation activity of cyclohexane over acid-treated Pt-supported sepiolite catalyst is much higher than that of Pd / Al2O3 The results also show that the electron effect on the Pt / sep-Al2O3 catalyst is more significant than the geometric effect on cyclohexane dehydrogenation.
