Abstract:

Nickel phosphide Ni2P catalysts supported on TiO2-Al2O3 support were prepared by co-impregnation. The catalysts were characterized by XRD, BET, and XPS. The effects of calcination temperature on catalyst structure and HDS activity were studied. The results indicated that the catalyst prepared with calcination temperature of 773 K exhibited the best performance. At a reaction temperature of 606 K, a pressure of 3.0 MPa, a hydrogen/oil ratio of 500 (V/V), and a weight hourly space velocity (WHSV) of 2.0 h-1, the conversion of DBT HDS was 96.0%.
