Hydrodesulfurization of Dibenzothiophene and its Hydrogenated Intermediates Over Bulk Ni2P

Abstract: A bulk Ni 2 P catalyst was prepared by co-precipitation of nickel phosphate followed by in situ temperature-programmed reduction (TPR) with H 2 . The hydrodesulfurization (HDS) of dibenzothiophene (DBT) and its hydrogenated intermediates 1,2,3,4-tetrahydrodibenzothiophene (TH-DBT) and 1,2,3,4,4a,9b-hexahydrodibenzothiophene (HH-DBT) was studied at 340°C and 4 MPa both in the presence and absence of piperidine (Pi). Bulk Ni 2 P exhibited a relatively low hydrogenation/dehydrogenation activity but high desulfuri… Show more

“…Thus, BCH and DM-BCH must be the products of the HDS of dodecahydrodibenzothiophene (DH-DBT) and DH-4,6-DMDBT, respectively. This agrees with results obtained over Ni 2 P and MoP [10][11][12].…”

“…This allows a detailed comparison of the HDS performance of Ni 2 P, MoP, and WP. It should be addressed that the bulk Ni 2 P catalyst was synthesized with P in excess (Ni/P molar ratio of 1.0) [10]. The hydrogenation/dehydrogenation activity of WP is stronger than that of Ni 2 P and MoP, as can be concluded from the following facts.…”
