PROBLEM TO BE SOLVED: To provide a method for isomerizing an aromatic compound containing 8 carbon atoms. ;SOLUTION: This method for isomerizing an aromatic compound containing 8 carbon atoms characteristically comprises using a catalyst which contains a zeolite having at least one EUO type structure and at least one metal or metal compound from the group VIII and introducing hydrogen and at least one compound having about 80°C to about 135°C carbon atoms an aromatic compound containing 8 carbon atoms together with raw materials containing one or more compounds to be isomerized to a reaction zone.;COPYRIGHT: (C)1999,JPO
