| 摘 要： | 对制备方法相同、活性相近的HM_(H~+)和HM_(NH_4~+)的酸强度分布(以NH_3的脱附活化能表征)和歧化中心在强酸中心中的分布状况作了比较。通过TPR与脉冲微反及流动法实验结果的比较,显示出在TPR中HM主孔道内的扩散限制。

| Abstract: | The distribution of acidic strength (expressed by E_4, the desorption activation energy of NH_(?)) and distribution of the disproportionate sites in the strong acid sites between two samples, HM_(H~+) (exchanged by HCl) and HM_(NH_4~+)(exchanged by NH_4Cl), prepared in the way and having approximately the same reactivity have been compared.By comparing the results of TPR with those of pulse and flow technique, it was found that TPR was limited by diffusion in the main channel of HM. |
