| 摘 要： | 在柱撑黏土Ti-PILCs的合成过程中，加入各种表面活性剂进行改性，通过负载Zn制备了Zn/Ti-PILCs吸附剂，考察了其对模拟柴油中二苯并噻吩的选择吸附性能。结果表明，经表面活性剂尤其是十六烷基三甲基溴化铵（CTAB）改性制备的Zn/Ti-PILCs其吸附脱硫率得以显著提高。当CTAB/Ti摩尔比为0.5时，Zn/Ti-PILCs-CATB具有最佳的吸附性能，DBT去除率达96.3%。N2吸附脱附等温线和孔径分布研究表明，CTAB改性可增加1nm～4nm孔的数量，并改善黏土层间柱子的分布，使Ti-PILCs具有更高的比表面及更均匀的孔径分布。

| Abstract: | Various surfactants were added during the synthesis of pillared clays Ti-PILCs to modify their structure and properties.Zn supported on the surfactant-modified Ti-PILCs(Zn/Ti-PILCs) was used as a desulfurization adsorbent and its performance in desulfurization of a model diesel oil containing dibenzothiophene(DBT) was investigated.The results showed that the capability of Zn/Ti-PILCs for DBT selective adsorption is enhanced by the surfactant modification.Especially,Zn/Ti-PILCs-CTAB obtained through modifica... |
