The Synthesis of Bulk Ni-Mo-W Hydrodesulphurization Catalysts with High Activity by Using Methylcellulose

摘要

Bulk Ni-Mo-W hydrodesulphurization catalysts with high surface areas were synthesized by using thermoreversible polymer hydrogels–methylcellulose. The surface area of the sample by this method is above 140 m~2/g and pore volume is 0.23 mL/g, which is much higher than that of catalyst without using methylcellulose. Xray diffraction results show that the use of methylcellulose has almost no influence on the structure of bulk Ni-Mo-W hydrodesulphurization catalysts.Hydrodesulphurization activity of the sample by using methylcellulose was much higher than that of the sample without using methylcellulose.
