| 英文摘要 | The characteristic features of acidic species and metallic lewis species in HZSM-5, Zn/HZSM-5, NaHZSM-5 and NaZnHZSM-5 have been studied by using the chemical and physical methods of NH3-TPD, TR-OH, Py-IR, CO-IR and XPS. The aromatization of ethane and ethene has been investigated over the catalysts, II is evidenced that a new kind of active sites-Zn2+-L acid center was formed which lead to the decrease of Brownsted acid of ZSM-5 zeolite, Zn2+-L acid is found to be a strong acid center, Impregnation of NaOH on zeolites also leads to the decrease of Brownsted acid. The aromatization selectivity and activity of ethane and ethene have a close relation with bifunctional center of Zn2+-L acid and Brownsted acid and there is an optimum balance between the metal content and Brownsted acid, Therefore, there exists an optimum zinc content in Zn/HZSM-5 catalysts during the aromatization of ethane and ethene. |
