The effect of neodymium content on dibenzothiophene HDS performance over a bulk Ni2P catalyst

• Nd modified unsupported Ni2P (NdxNi2P) catalysts have been successfully prepared.
• Nd can promote the formation of smaller and highly dispersed Ni2P particles.
• An appropriate amount of Nd can dramatically increase the surface area.
• The NdxNi2P catalysts show much higher HDS activity compared to the bulk Ni2P.

Neodymium (Nd)-modified Ni2P catalysts (NdxNi2P, where x is the molar fraction of Nd to Ni2P) have been successfully prepared. An appropriate amount of Nd can dramatically increase the surface area and promote the formation of smaller and highly dispersed Ni2P particles. The NdxNi2P catalyst with x = 0.10 exhibited the highest dibenzothiophene hydrodesulfurization activity of 97.4%, which is an increase of 35% when compared with that found for bulk Ni2P.
