Preparation of Nano Ni₂P/TiO₂-Al₂O₃ Catalyst and Catalytic Activity for Hydrodesulfurization

Abstract:

nanonickel phosphide Ni₂P catalysts supported on TiO₂-Al₂O₃ support were prepared by impregnation. The catalysts were characterized by XRD, BET, and XPS. The effects of impregnation method,Ni₂P loading on catalyst structure and HDS activity were studied. The results indicated that co-impregnation method is beneficial to the formation of Ni₂P and can avoid the formation of Ni₁₂P₅. The catalyst prepared with co-impregnation method, Ni₂P loading of 30% 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%.
