  • Patent number: 6123834
    Abstract: A process for reforming naphtha-containing hydrocarbon feedstreams is disclosed wherein a naphtha stream containing at least about 5 wt % of C9+ aromatics, at least about 25 wt % C.sub.5 to C.sub.9 aliphatic hydrocarbons and greater than 50 wt. ppm sulfur is contacted under reforming conditions with a bifunctional reforming catalyst, e.g. H.sup.+ ZSM-5, containing a dehydrogenation metal, e.g. zinc. The resulting reformate contains a higher ratio of C.sub.6 to C.sub.9 aromatics to C.sub.5 -C.sub.9 aliphatic hydrocarbon which boil near the boiling point of C.sub.6 to C.sub.8 aromatics present in the reformate, thereby facilitating separation of these aromatics form the reformate.
