A multi-zone process for the conversion of a hydrocarbon feedstock
comprising cyclic compounds to produce aromatic compounds, and in
particular xylene compounds. A naphtha boiling range stream having a
boiling point range from about 71.degree. C. (160.degree. F.) to about
216.degree. C. (420.degree. F.) is reformed and/or transalkylated within
reforming and transalkylation zones to produce an aromatics-rich
high-octane stream containing xylene with increased xylene purity.
