Processes and apparatus are provided that provide high yields of xylenes
per unit of aromatic-containing feed while enabling a high purity benzene
co-product to be obtained without the need for an extraction or
distillation to remove C.sub.6 naphthenes. The processes of this
invention include a transalkylation section and a disproportionation
section in the benzene and toluene-containing feed is directly provided
to the transalkylation section and in which a benzene recycle loop in the
transalkylation section isolates the disproportionation section from
C.sub.6 naphthenes.
