Abstract

PURPOSE:To extremely reduce ethylbenzene concentration of 8C aromatic hydrocarbon mixture, by bringing the 8C aromatic hydrocarbon mixture into contact with a specific hydrogenating and deethylating catalyst in the presence of hydrogen before the 8C aromatic hydrocarbon mixture is circulated through a p-xylene separating process and a xylene isomerizing process. CONSTITUTION:In producing p-xylene 11 by feeding 8C aromatic hydrocarbon mixture 1 consisting of ethylbenzene to a circulation system comprising a p- xylene separating process 10 and a xylene isomerizing process 12, before the mixture 1 is fed to the circulation system, the mixture is brought into contact with a deathylating reactor 2 for ethylbenzene having a hydrogenating and deathylating catalyst comprising a metal having hydrogenating activity and zeolite of acid type so that ethylbenzene in the mixture is mainly converted to benzene, ethylbenzene concentration in the mixture is reduced to such a degree (<=1wt.%) as to be regarded substantially zero and reduction in the labor amount used in the separating and/or isomerizing process is aimed.
