摘要：

Silica-dispersed NiMoW trimetallic hydrodesulfurization catalysts were prepared by deposition-precipitation method For comparative purposes, bulk NiMoW trimetallic catalysts were obtained by co-precipitation Silica was employed to disperse active metals for full utilization of active components and silica dispersed NiMoW catalyst had high active metal content BET analysis showed that silica-dispersed NiMoW trimetallic catalysts had a high surface area (165 1 m(2)/g) and pore volume (0 27 ml/g) Transmission electron microscopy results proved that active components were well dispersed Hydrodesulfurization activity of silica-dispersed NiMoW catalysts was much higher than that of comparative catalysts and up to twice greater than those of commercial NiMo alumina-supported systems per gram of catalyst
