HYDRODESULFURIZATION PROCESS

In one aspect, a hydrodesulfurization process is provided that selectively desulfurizes a hydrocarbon stream with minimal olefin saturation and minimal recombination of sulfur into mercaptans. In another aspect, the process includes a multi-stage reaction zone including at least first and second ser...

More Information
Summary:In one aspect, a hydrodesulfurization process is provided that selectively desulfurizes a hydrocarbon stream with minimal olefin saturation and minimal recombination of sulfur into mercaptans. In another aspect, the process includes a multi-stage reaction zone including at least first and second serial hydrodesulfurization reaction zones that sequentiall y remove sulfur from a hydrocarbon stream. In yet another aspect, the process is particularly suite d to selectively desulfurize an olefinic naphtha hydrocarbon stream, such as FCC naphtha, ste am cracked naphtha, coker naphtha, or other gasoline boiling hydrocarbon streams.</SDOA B>
