Abstract:
A process comprising catalytically isomerising aromatic compounds containing eight carbon atoms, wherein the catalyst used contains at least one zeolite with an EUO structure and at least one metal or a compound of a metal from group VIII, and hydrogen and a recycle stream consisting essentially of compounds with a boiling point of about 80Â° C. to about 135Â° C. other than said aromatic compounds containing eight carbon atoms is introduced into the reaction zone with the feed containing the eight carbon atom aromatic compound or compounds to be isomerized, withdrawing an isomerizate from the reaction zone, separating said isomerizate to remove compounds having boiling points below about 80Â° C. and above about 135Â° C., and recycling at least a fraction of the resultant isomerizate as said recycle stream.
