摘要：

The hydrodesulfurization (HDS) activity of nano-sized HZSM-5 catalyst modified by different nickel species was measured with full-range FCC gasoline as feedstock. The results indicated that the nano-sized HZSM-5 catalyst modified by NiSO4 showed more stable HDS activity than the nano-sized HZSM-5 catalyst modified by NiO. The characterization of FT-IR spectra before and after pyridine adsorption, ammonium temperature-programmed desorption, and differential thermogravimetry showed that there was a strong interaction between SO42- and Al2O3 in the catalyst modified by NiSO4 The interaction increased both the amount and the strength of acid sites by creating a kind of acidity, being like super acid.
