    Abstract: 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 (16) having a boiling point range from 71°C (160°F) to 216°C (420°F) is reformed and/or transalkylated within reforming and transalkylation zones (18) to produce an aromatics-rich high-octane stream (36) containing xylene with increased xylene purity.

    Abstract: Vapor-liquid contacting apparatuses, for example reactors and distillation columns (as well as reactive distillation apparatuses), comprising a vessel with one or more vortex contacting stages, are described. The one or more stages provide high interfacial area for the effective contacting of the different phases, in addition to the effective disengagement of these phases after contacting.
