Title
Hydrodesulfurization of dibenzothiophene over PtMo/MCM-48 catalysts
Abstract

•Synthesis of highly ordered MCM-48 material•Fast impregnation via insipient wetness method of platinum and molybdenum oxides•XPS characterization of the active phases on the MCM-48 surface•Good catalytic activity to the HDS of DBT

Catalysts of platinum and molybdenum supported on MCM-48 materials were synthesized and characterized by XRD, XPS and N2 adsorption–desorption. Catalytic activity was evaluated in the model reaction of hydrodesulfurization of dibenzothiophene. Catalytic results showed high catalytic performance of ca. 95% for PtMo/MCM-48 catalyst with the formation of biphenyl (BP) as the main product, typical from direct hydrodesulfurization (DDS) pathway and ciclohexylbenzene (CHB) in a minor proportion from the hydrogenation prior to the desulfurization pathway.
