摘　　要：Diatomite-dispersed NiMoW catalyst was prepared and characterized,and the activity of catalyst samples was tested during the HDS reaction of FCC diesel.Sulfur compounds in the feedstock and the hydrogenated products obtained over different catalysts were determined by GC-PFPD.The test results showed that the diatomite-dispersed NiMoW catalyst had high hydrodesulfurization activity for FCC diesel,which could be contributed to the excellent hydrogenation performance of the said catalyst.Characterization of catalyst by TEM and XRD indicated that the diatomite-dispersed NiMoW catalyst possessed higher layer stacking,larger curvature of MoS2or WS2,and segregated Ni3S2crystals relative to the supported catalyst.This kind of structure leads to high hydrogenation activity of the diatomite-dispersed NiMoW catalyst.Diatomite-dispersed NiMoW catalyst was prepared and characterized, and the activity of catalyst samples was tested during the HDS reaction of FCC diesel.
