ABSTRACT:
A process for removing organic sulfur from a fuel gas stream that further contains light olefins by catalytic hydrodesulfurization to yield a treated fuel gas having an very low concentration of organic sulfur. The effluent of the catalytic hydrodesulfurization reactor may be cooled with a portion thereof being recycled and introduced along with the fuel gas stream that is charged to the hydrodesulfurization reactor. The remaining, unrecycled portion of the effluent may further be treated to remove the hydrogen sulfide that is yielded from by the hydrodesulfurization of the fuel gas stream.
