中文摘要：

用4 mol·L-1Na2CO3溶液处理ZSM-5分子筛[HZSM-5（C）],处理后的分子筛采用n（TPAOH）∶n（Si O2）=0.2∶1的TPAOH溶液进行二次晶化[HZSM-5（C-T）]。制备了Ni-Mo/HZSM-5（原粉）、Ni-Mo/HZSM-5（C）和Ni-Mo/HZSM-5（C-T）催化剂。在小型连续固定床反应器上,考察了Ni-Mo/HZSM-5,Ni-Mo/HZSM-5（C）和Ni-Mo/HZSM-5（C-T）催化剂的硫醚化反应性能。结果表明：Na2CO3处理形成了微-介孔多级孔HZSM-5分子筛,提高了硫醇转化率;TPAOH二次晶化,修复了分子筛的孔道,增加了介孔的数量,进一步提高了硫醇的转化率。考察了TPAOH二次晶化前后,HZSM-5分子筛的热稳定性和水热稳定性。结果表明：Na2CO3处理降低了HZSM-5分子筛的热稳定性和水热稳定性,而TPAOH二次晶化,提高了HZSM-5分子筛的热稳定性和水热稳定性。

英文摘要：

ZSM-5 zeolite was treated by Na2CO3 （4 mol·L-1 ） and then it was secondarily crystallizated by TPAOH [ n（TPAOH） ： n（ SiO2 ） = 0.2：1 ]. The catalysts of Ni-Mo/HZSM-5 （ the raw powder）, Ni-Mo/HZSM-5 （C） and Ni-Mo/HZSM-5 （C-T） were prepared. The performance of thioetherification was investigated on the small-scale fixed bed reactor. The results showed that microporous and mesoporous were formed on ZSM-5 zeolite after treated by Na2CO3, and the conversion rate of mercaptan was improved. The framework of zeolite was restored , the quan- tity of mesoporous increased after secondarily crystallizated by TPAOH and the conversion rate of mercaptan was further improved. The thermal stability and hydrothermal were discussed, and these properties of HZSM-5 （C） were stability of HZSM-5, HZSM-5 （C） and HZSM-5 （C-T） lower, but the properties of HZSM-5 （C-T） were higher.
