A process for the hydrodesulfurization (HDS) of multiple condensed ring heterocyclic organosulfur compounds present in petroleum and petrochemical streams over noble metal-containing catalysts under relatively mild conditions. The noble metal is selected from Pt, Pd, Ir, Rh, and polymetallics thereof. The catalyst system also contains a hydrogen sulfide sorbent material.

[ What is claimed is:] [1.] A process for the substantially complete desulfurization of distillate streams containing condensed ring sulfur heterocyclic compounds, which process comprises contacting said stream with a catalyst system comprised of: (a) a hydrodesulfurization catalyst comprised of a noble metal selected from the group consisting of Pt, Pd, Ir, Rh, and polymetallics thereof, on an inorganic refractory support; and (b) a hydrogen sulfide sorbent material; wherein the hydrodesulfurization conditions include temperatures from about 40.degree. C. to 500.degree. C., and pressures from about 100 to 3,000 psig, wherein both the catalyst and the hydrogen sulfide sorbent material are present on the same composite particles.
