| 中文摘要 | The Pt-Sn-based catalyst was intensified using SAPO-34 as support for direct propane clehydrogenation to propylene. The catalyst was prepared by sequential impregnation method and characterized by XRF, BET, XRD, NH3-IR, NH3-TPD, H-2-TPR, HR-TEM and O-2-pulse coke analysis. NH3-TPD, IR spectra and XRD results suggested that the doping of metals on SAPO-34 did not affect its acidic strength and structural topology of support, respectively. Propylene selectivity of 94% and total olefins selectivity greater than 97% was achieved using Pt-Sn/SAPO-34. The results were compared with Pt-Sn/ZSM-5 under identical conditions. The possible reasons for improvement were the larger surface area, shape selectivity and particular by suitable acidity of SAPO-34. (C) 2009 Elsevier B.V. All rights reserved. |
