Abstract

•Rare earth yttrium (Y) modified bulk Ni2P (YxNi2P) catalysts were described.•Y can promote the formation of more active Ni2P phase.•Y can greatly increase the surface area of catalyst.•Y promotes a smaller crystallite size and better dispersion of active Ni2P particles.•The YxNi2P catalysts showed much higher HDS activity than the bulk Ni2P catalyst.

Yttrium-modified bulk Ni2P (YxNi2P) catalysts showing high hydrodesulfurization (HDS) activity are described. The incorporation of Y into the bulk Ni2P catalyst can suppress the formation of the Ni5P4 phase and therefore promote formation of the more active Ni2P phase. Y can also greatly increase the surface area of the catalyst, leading to a smaller crystallite size and better dispersion of active Ni2P particles. The obtained YxNi2P catalysts show much higher Dibenzothiop (DBT) HDS activity than the bulk Ni2P catalyst.
