| 摘 要： | 以水热处理的纳米HZSM-5为载体,通过螯合剂乙二胺四乙酸(EDTA)改性制备了一种具有较高脱硫活性和稳定性的EDTA-NiMo/HZSM-5催化剂,并用XRD、ICP、FT-IR、27Al MAS NMR、TG-DTA、Py-IR及NH3-TPD对催化剂进行了表征.结果表明,EDTA与载体之间具有较强的相互作用,这种强相互作用减弱了金属活性组分与载体之间的作用力,抑制非活性NiAl2O4、Al2(MoO4)3的形成，有利于活性组分在载体表面的分散,且添加的螯合剂与金属组分镍可以形成稳定的螯合物,在硫化过程中能改变催化剂的硫化顺序,促使有效脱硫活性中心的形成,提高了催化剂的脱硫活性和稳定性.

| Abstract: | A new type of EDTA-NiMo/nano-HZSM-5(EDTA=ethylene-diaminetetraacetic acid) catalyst for FCC gasoline hydrodesulfurizaiton was prepared and characterized by XRD,ICP,FTIR,27Al MAS NMR,TG-DTA,Py-IR and NH3-TPD.The catalyst showed higher and more stable hydrodesulfurization(HDS) activity for FCC gasoline than the NiMo/nano-HZM-5 catalyst.The results indicated that there was a strong interaction between EDTA and nano-HZSM-5,which weakened the interaction between the active metal components and support,improved d... |
