Unsupported NiMoW sulfide hydrodeoxygenation (HDO) catalysts were prepared by mechanical activation method varying the nickel concentration. Catalysts were characterized by XRD, SEM, TEM and BET surface area measurements. Moreover, catalytic activity and selectivity were evaluated in the HDO of 4-methylphenol (4-MP). The results suggested that the structure and the promoting effects were strongly dependent on the amount of Ni added into the catalysts. Nickel gave a positive effect on HDO of 4-MP and modified the product selectivity slightly. It was also found that nickel played a crucial role in the variation of catalytic performance.
Graphical abstractEffect of nickel content on the activity and product selectivity over unsupported NiMoW catalysts in the HDO of 4-methylphenol.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► Unsupported NiMoW catalysts were synthesized by mechanical activation method. ► Catalysts with different nickel content favored DDO pathway in the HDO of 4-methylphenol. ► The addition of nickel improved the catalytic activity. ► The promoter played a complex role in the structure and catalytic performance of the catalysts.
