Isomerization with an EUO-type catalyst of aromatic compounds with eight carbon atoms followed by a dehydrogenation stage

摘要

A C.sub.8 aromatic feedstock is isomerized by an isomerization stage conducted at 320-380° C. with a catalyst containing at least one EUO-structure-type zeolite and at least one metal of group VIII, to obtain an effluent containing isomerized alkyl aromatics and about 10-30% by weight of naphthenes. The effluent is then subjected to a dehydrogenation stage so as to convert the naphthenes to additional alkyl aromatics.
