摘　　要：采用金属离子直接插入法合成了Cu-MCM-41吸附剂,在100℃的条件下,研究了吸附剂对商业化的FCC柴油的吸附性能.结果表明,处理5·5ml柴油之后,Cu-MCM-41的脱硫效率仍可达84%以上.这意味着噻吩及其衍生物容易通过π-络合过程发生吸附,并且Cu-MCM-41对噻吩类化合物具有较高的吸附选择性.The Cu-MCM-41 adsorbent was synthesized by direct insertion of a metal ion as a precursor. The adsorption performance of the adsorbent for commercial fluid catalytic cracking diesel was investigated at room temperature and 100 ℃, respectively. The sulfur removal efficiency of Cu-MCM-41 was still higher than 84% after 5.5 ml diesel was treated at 100 ℃. This means that thiophene and thiophene derivatives favorably adsorb on Cu active sites by a π-complexation process, and the adsorption of sulfur-containing aromatic compounds over Cu-MCM-41 is highly selective.
