A Ni-W catalyst was prepared by impregnation method using aluminum hydroxide mixed with zeolite as carrier.Catalysts were characterized by BET and Py-IR.The activity of catalysts for hydrogenation was tested using FCC diesel fuel as feedstock.Results showed that the catalyst was more acidic as a result of the carrier mixed with zeolite which was provided for the raising of diesel fuel＇s cetane number.The most appropriate process conditon of this catalyst for FCC diesel fuel hydrogenation was 350 ℃,7 MPa,450：1,and 1.0 h-1.
