A process for the hydrodesulfurization (HDS) of multiple condensed ring heterocyclic organosulfur compounds present in petroleum and petrochemical streams and the saturation of aromatics over noble metal-containing catalysts under relatively mild conditions. The noble metal is selected from Pt, Pd,...
