摘要

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.
