| 摘 要： | 考察了喹啉存在时 Ni-Mo/MCM-41、Ni-Mo/MCM-41-Y(C)和Ni-Mo/MCM-41-Y(M)催化剂对二苯并噻吩（DBT）的加氢脱硫(HDS)活性，研究了载体孔道及酸性位的分布对催化剂耐氮性能的影响。结果表明，喹啉对DBT 加氢脱硫的加氢反应路径存在明显的抑制作用，而对氢解反应路径没有抑制作用。喹啉对DBT 加氢脱硫的氢解反应和加氢反应路径的不同作用，表明 DBT 在Ni-Mo 催化剂上进行HDS 时氢解反应和加氢反应可能发生在不同的活性位。孔道结构和酸性位的分布不同的Ni-Mo/MCM-41-Y(M)催化剂的耐氮能力弱于Ni-Mo/MCM-41-Y(C)催化剂，表明载体的孔道结构和酸性位的分布对催化剂的耐氮性能具有重要影响。 |
| 关 键 词： | 喹啉；加氢脱硫 耐氮 |

| Abstract: | The effects of quinoline on the hydrodesulfurization(HDS) activity of Ni-Mo/MCM-41,Ni-Mo/MCM-41-Y(M) and Ni-Mo/MCM-41-Y(C) were investigated by the HDS test of dibenzothiophene(DBT).The inhibition of quinoline on the pathways of hydrogenolysis and hydrogenation was different,implying that the hydrogenolysis and hydrogenation reaction occurred on different active centers of the catalyst.The different nitrogen-tolerant abilities of Ni-Mo/MCM-41-Y(M) and Ni-Mo/MCM-41-Y(C) catalysts were caused by different por... |
| Keywords: | quinoline hydrodesulfurization nitrogen-tolerant |
