英文摘要Pt/WOx-ZrO2 and Pt/ZSM-22 were prepared and used as catalysts for the n-pentane hydroisomerization reactions. The physico-chemical properties of the supports were characterized by XRD, N-2 adsorption, NH3-TPD and 1-pentene isomerization reaction. The reducibility and adsorbability of the catalysts were evaluated via H-2-TPR, H-2-TPD and CO adsorption. Under the reaction condition of WHSV = 1 h(-1), Pn-pentane,0 = 0.24bar and ambient pressure, the yields of isopentane over Pt/WOx-ZrO2 and Pt/ZSM-22 can reach 52% (at 300 degrees C) and 61% (at 340 degrees C) respectively. The selectivities to isopentane over these two catalysts are well above 95%. The hydroisomerization mechanisms over these catalysts are discussed. (C) 2017 Elsevier B.V. All rights reserved.
