| 摘 要： | 在柴油加氢脱硫(HDS)催化剂FHUDS-5(Co-Mo/Al2O3)上,模拟工业高压搅拌反应釜生产工艺,考察了喹啉对二苯并噻吩(DBT)HDS反应活性的影响,并对其反应动力学进行了研究。结果表明,DBT的HDS反应主要通过加氢路径(HYD)和氢解路径(DDS)进行,符合一级反应动力学模型;当喹啉浓度很低时,其对DBT加氢脱硫反应的抑制作用强烈,但随着喹啉浓度的增加,这种抑制作用不再明显;当n为0.25时,喹啉对DBT加氢脱硫反应活性的影响符合于rDBT=kDBTCDBT/(1+Kn NCn N)动力学模型。

| Abstract: | The effect of quinoline on the hydrodesulfurization （HDS） of dibenzothiophene（DBT） and its reaction kinetics were investigated over diesel HDS catalyst FHUDS-5 （Co-Mo/Al2O3） by simulating industrial agitated autoclave process.The results showed that the hydrodesulfurization of DBT was realized through hydrogenation and hydrogenolysis,and both of the reactions followed the first-order kinetic equation.Low concentration quinoline had significant inhibition effect on hydrodesulfurization of DBT,while with the increase of quinoline concentration,the effect decreased obviously.When n was 0.25,the effect obeyed kinetic equation rDBT =kDBTCDBT/（1 ＋ KnNCnN）. |
