Abstract
A process for the selective hydrodesulfurization of naphtha streams containing sulfur and olefins. A substantially olefins-free naphtha stream is blended with an olefins/sulfur-containing naphtha stream and hydrodesulfurized resulting in the substantial removal of sulfur without excessive olefin saturation.
