Abstract: Charge aromatic streams, such as C6-C11 aromatic streams, may be treated to separate a C7-C8 stream, a benzene stream, and a heavier stream. At least a portion of the heavier stream is treated to lower its content of fused polycyclic hydrocarbons; and the denuded heavier stream is transalkylated with the benzene stream. The remaining portion of the heavier stream is dealkylated to give increased yield of C7-C8 aromatics.

Abstract: A charge aromatic stream, such as a C6-C12 stream, is typically treated to separate out an intermediate C7-C8 aromatic stream. The light stream, e.g. benzene, is transalkylated with the C9-C12 component of the charge to form additional C7-C8; and excess C9C12 (over and above that used in transalkylation) is dealkylated to C6-C8. The C6 portion of the dealkylate is used in transalkylation.
