A process for the selective hydrodesulfurization of olefinic naphtha
streams containing a substantial amount of organically-bound sulfur and
olefins. The olefinic naphtha stream is selectively desulfurized in a
hydrodesulfurization reaction stage. The hydrodesulfurized effluent
stream is separated into a light and heavy liquid fraction and the
heavier fraction is further processed in a mercaptan destruction reaction
stage to reduce the content of mercaptan sulfur in the final product.
