The CeUSY zeolites loaded with Ce were prepared by liquid phase ion exchange method,and the Ni contamination was conducted by Mitchell impregnation method. The texture properties were characterized by inductively coupled plasma atomic emission spectrometry( ICP-AES), X-ray diffraction( XRD) and N_2 adsorption. Moreover,the nickel tolerance was evaluated by the MAT evaluation device. The results showthat CeUSY zeolites with different Ce contents possess a nickel tolerance performance varying in a volcano typ...
