摘要： Hydrocarbon feeds are upgraded by contact of the stream under hydrodesulfurization (HDS) conditions with a catalyst system comprising a sulfided, transition metal promoted tungsten/molybdenum HDS catalyst, e.g., Ni/Co--Mo/Al.sub.2 O.sub.3 and a solid acid catalyst which is effective for the isomerization/disproportionation/transalkylation of alkyl substituted, condensed ring heterocyclic sulfur compounds present in the feedstream, e.g. zeolite or a heteropolyacid compound. Isomerization, disproportionation and transalkylation reactions convert refractory sulfur compounds such as 4- or 4,6-alkyl dibenzothiophenes into corresponding isomers or disproportionated isomers which can be more readily desulfurized by conventional HDS catalysts to H.sub.2 S and other products.
