Abstract: Ni-W/Al₂O₃ catalysts for heavy oil hydrotreating were prepared with incipient wetness impregnation,and the effects of zirconium step-impregnated and co-impregnated on the catalytic performance were studied.The catalysts were characterized with H₂-TPR,HRTEM,UV-Vis and XPS techniques.The results showed that zirconium weakened the strong interaction between active metals and Al₂O₃ support,increased the stacked layers of WS₂ active phase,zirconium step-impregnated promoted the sulfidation of active metals and increased the dispersion of W species on catalysts surface.Ni-W catalysts prepared with zirconium step-impregnated had outstanding hydrodesulfidation and hydrodenitrogenation performance for Venezuelan deasphalted oil.

Key words: Zr-modified, hydrodesulfidation, hydrodenitrogenation, catalyst
