PROBLEM TO BE SOLVED: To provide a hydrodesulfurization process that, in one aspect, selectively desulfurizes a hydrocarbon stream with minimal olefin saturation and minimal recombination of sulfur into mercaptans. SOLUTION: The hydrodesulfurization process includes a multi-stage reaction zone including at least first and second serial hydrodesulfurization reaction zones that sequentially remove sulfur from the hydrocarbon stream. The hydrodesulfurization process is particularly suited to selectively desulfurize an olefinic naphtha hydrocarbon stream such as FCC naphtha, steam cracked naphtha, coker naphtha or other gasoline boiling hydrocarbon streams.
