| 摘 要： | 通过研究直馏、焦化及催化柴油的含硫化合物的结构与分布、含硫量、含氮量以及芳烃含量等性质差异,采用Co-Mo和Ni-Mo-W两种柴油深度脱硫催化剂对比考察了不同柴油的深度脱硫效果。研究结果表明:直馏柴油采用Co-Mo型催化剂效果较好,焦化柴油和催化柴油采用Ni-Mo-W型催化剂更有利于烷基取代的苯并噻吩和二苯并噻吩的脱除。处理二次加工柴油时,Ni-Mo-W催化剂还具有较好的脱氮和芳烃饱和能力。

| Abstract: | Two catalysts,Co-Mo and Ni-Mo-W supported on γ-alumina,were used to evaluate the hydrodesulfurization effect of three typical diesel oils by analyzing their properties including sulfur content,sulfur compound structures and distributions,nitrogen content and aromatic content.Results showed that Co-Mo catalyst was more effective in sulfur removal when treating straight run gas oil.In the case of delayed coker diesel and FCC normal light cycle oils,Ni-Mo-W catalyst showed a better performance for removing benzothiophene,dibenzothiophene and their derivates than Co-Mo catalyst.For secondary processed diesel oils,Ni-Mo-W showed higher ability for denitrogenation and aromatic saturation compared to Co-Mo. |
