摘要： A method is provided for removing sulfur from an effluent produced by hydrotreating a hydrocarbon feed, said effluent having a heavy fraction containing polyaromatic sulfur compounds and a lighter fraction, said method comprising contacting the effluent with a noble metal containing hydrodearomatization catalyst on a support under super-atmospheric hydrogen pressure and reaction conditions sufficient to hydrogenate at least one ring of said polyaromatic sulfur compounds and thereby produce a product with a reduced sulfur content.
