An Unexpected Pathway For Hydrodesulfurization Of Gazole Over A Comos Active Phase Supported On A Mesoporous Tio2 Catalyst

Using dual mesoporous titania as a support, due to the presence of intrinsic Bronsted acid sites, the main approach to 4,6-dimethylbenzo-thiophene (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) MoS2/Al2O3 catalyst.
