Synthesis and Hydrodesulfurization Performance of NiMo Sulfide Catalysts Supported on γ-Al2O3


Article Preview

This work presents the synthesis and hydrodesulfurization performance of NiMo sulfide catalysts supported on γ-Al2O3 during the hydrodesulfurization (HDS) of dibenzothiophene (DBT). The catalysts were synthesized by the co-impregnation method using an atomic ratio of Ni=Ni/(Ni+Mo)=0.5. The materials were characterized by N2 physisorption, XRD and HRTEM. This catalyst exhibited the larger pore size and high specific surface area, as well as better morphological properties. The catalytic activity was evaluated using a high-pressure batch reactor at 280 °C and 3.0 MPa. The catalytic activity during HDS-DBT indicated that the NiMoS/γ-Al2O3 catalyst was better than that NiMoS/γ-Al2O3 catalyst. the NiMoS/γ-Al2O3 catalyst exhibits higher DDS selectivity (3.0) than NiMo/γ-Al2O3 catalyst (2.55).
