中文摘要：

用 Na2 CO3、TPAOH 和 TPA＋／CO32－混合碱分别处理 HZSM－5分子筛，采用 FT－IR、XRD、XRF、N2吸附脱附、SEM、NH3－TPD 及 Py－FTIR 表征手段对各类碱处理前后的 HZSM－5分子筛进行表征。结果表明，3种类型的碱处理H ZSM－5分子筛后，均能形成微孔－介孔多级孔道的 HZSM－5（A）催化剂，并能调变催化剂的酸性，其中，TPA＋／CO32－混合碱处理得到的 HZSM－5（TPA＋／CO32－）催化剂，比表面积最大，介孔数量最多。在小型固定床反应器上，考察了 HZSM－5和 HZSM－5（A）催化剂的噻吩烷基化性能，结果表明，HZSM－5（TPA＋／CO32－）催化剂因为具有适当的多级孔孔道和较多的 B 酸中心而表现出较高的噻吩转化率和1－己烯对噻吩的选择性。

英文摘要：

HZSM-5 zeolites were respectively treated by Na2 CO3 ,TPAOH and mixed alkali solution of TPA＋/CO3 2-.The samples were cha racter ized by FT-IR XRD, XRF, N2 adsorption/desorption,S EM, NH3-TPD and Py-FTIR techniques.It was found that the microporous and mesoporous hierarchical HZSM-5 （A） catalysts were formed after the treatment and their acidity were modulated.The largest surface area and the most mesoporous were found in the HZSM-5 （ TPA＋/CO3 2-） treated by the mixed alka li of TPA＋/CO3 2-s.The thiophene alkylation performance of HZSM-5 and HZSM-5（A） zeolites was investigated in a small-scale fixed bed reactor with model compounds as feedstock.The co-sequences displayed that HZSM-5 （ TPA＋/CO3 2-） catalysts exhibited the higher conversion of thiophene and selectivity of 1-hexene because the zeolites had proper hierarchical pore diameter and more B-acid sites.
