An unexpected pathway for hydrodesulfurization of gazole over a CoMoS active phase supported on a mesoporous TiO 2 catalyst

An unexpected pathway for hydrodesulfurization of gazole over a CoMoS active phase supported on a mesoporous TiO 2 catalyst

Using dual mesoporous titania as a support, due to the presence of intrinsic Brönsted acid sites, the main approach to 4,6-dimethylbenzothiophene (46DMDBT) hydrodesulfurization (HDS) becomes the direct desulfurization (DDS) route through isomerization and dismutation reactions, instead of the hydrog...

Zusammenfassung:Using dual mesoporous titania as a support, due to the presence of intrinsic Brönsted acid sites, the main approach to 4,6-dimethylbenzothiophene (46DMDBT) hydrodesulfurization (HDS) becomes the direct desulfurization (DDS) route through isomerization and dismutation reactions, instead of the hydrogenation (HYD) pathway usually observed with a conventional promoted (by Ni or Co) MoS /Al O catalyst.
