Abstract: The carrier was modified by phosphorus followed by preparation of aromatic saturation catalyst for kerosene by incipient impregnation of Ni-W solution. The catalysts were characterized by BET, XRD, H2-temperature programmed reduction, diffuse reflectance ultraviolet-visible spectra techniques. The aromatic saturation activities under different reaction temperatures and reaction pressures were investigated. The results show that the appropriate reaction pressure is 6.0 MPa, and adjusting reaction temperature is the main means for optimizing the process conditions. Compared with unmodified catalyst and reference catalyst, the phosphorus modified catalysts have a significant higher aromatic saturation activity.
