Abstract

Hydrodesulfurization and hydrodenitrogenation of fossil and regenerable hydrocarbon feedstocks are key reactions to utilize feedstock and environmentally compatible. The presentation discusses the hydrogenation and hydrodefunctionalization of aromatic molecules using supported Pt and Pd-Pd, as well as MoS2 and Mo-Ni sulfide catalysts by combining the characterization of the active sites and detailed kinetic measurements. In contrast to intuition and while the specific sites are very different, the mechanisms of both reactions can be described by a surprisingly similar reaction network. In both cases the catalysts act as bifunctional materials combining the action of Brønsted and Lewis acid sites with sites that provide atomic hydrogen. The specific role of the metals involved and the potential and limitations of the catalysts will be discussed.
