摘要 考察了H2S存在时Ni-Mo/MCM-41、Ni-Mo/MCM-41-Y(M)和Ni-Mo/MCM-41-Y(C)催化剂的加氢脱硫(HDS)活性,研究了载体孔道及酸性位的分布对催化剂耐硫性能的影响。结果表明,H2S对DBT的HDS反应存在明显的抑制作用;H2S对DBT的HDS反应的氢解(DDS)反应和加氢(HYD)反应路径的抑制程度不同,表明DBT在Ni-Mo催化剂上HDS反应时DDS反应和HYD反应可能发生在不同的活性位上。Ni-Mo/MCM-41-Y(M)催化剂的耐硫能力强于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硫性能具有重要影响。 The effects of H2S 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 reaction of DBT.The effects of the pore structure and acid site distribution of the support on the sulfur-tolerant ability of Ni-Mo catalyst were studied.It was found that the inhibition of the H2S on the pathways of hydrogenolysis(DDS) and hydrogenation(HYD) were different,implying that DDS and HYD reaction occurred on different active centers.The different sulfur-tolerant abilities of Ni-Mo/ MCM-41-Y(M) and Ni-Mo/MCM-41-Y(C) catalysts were caused by different pore structures and different acid site distribution of the support.
