摘要: A process is provided for the isomerization of aromatic hydrocarbons including contacting an aromatic hydrocarbon feedstream with a catalyst comprising a hydrogenation metal wherein sulfur is continuously introduced after catalyst start-up for an extended period of time at a concentration of no more than 56 ppm by weight of the aromatic hydrocarbon feedstream.
