ABSTRACT:
In accordance with the the present invention, there is provided a process for the conversion of aromatic hydrocarbons including benzene to hydrocarbon components comprising primarily toluene. According to the invention, a catalyst reaction zone is established having a metal-loaded mordenite catalyst. A mixed feedstock of aromatic hydrocarbons, including benzene, xylene(s) and, optionally, ethylbenzene is introduced into the reaction zone and hydrogen is used as a cofeed to provide a reductive environment. The feedstock is contacted with the metal-loaded mordenite catalyst and the conversion of the aromatic hydrocarbon components is conducted under temperature and pressure conditions sufficient to effect the conversion of the feedstock to hydrocarbon components containing primarily toluene. Finally, the conversion product containing primarily toluene is recovered from the reaction zone.
