ABSTRACT:
A process for removing residual sulfur from a hydrotreated naphtha feedstock is disclosed. The feedstock is contacted with molecular hydrogen under reforming conditions in the presence of a less sulfur sensitive reforming catalyst, thereby converting trace sulfur compounds to H.sub.2 S, and forming a first effluent. The first effluent is contacted with a solid sulfur sorbent, removing the H.sub.2 S and forming a second effluent. The second effluent is contacted with a highly selective reforming catalyst under severe reforming conditions.
