Sulfided NiMoS/CNTs hydrogenation catalyst with Mo-Ni as the major active component was prepared with CNTs as support and sulfurization precursor ammonium tetrathiomolybdate as molybdenum source，by incipient wetness impregna
tion method.The hydrodesulfurization（HDS） performance of dibenzothiophene（DBT） on NiMoS/CNTs catalyst by using flow microhigh pressure reactor was researched and compared with NiMoS/γ-Al2O3.The evaluation results indicated that，NiMoS/CNTs catalyst has much higher HDS activity and selectivity than NiMoS/γ-Al2O3 catalyst.The CNTs-supported NiMoS/CNTs catalyst has a lower initial reduction temperature，higher molybdenum disulfide stacking layer，higher Mo4+ atomic ratio，suita
ble molybdenum disulfide wafer length and high density of active site，which is the main reason for high performance of hy
drogenation catalyst.
