Abstract: An improved reforming process for producing aromatic hydrocarbons is disclosed. The process includes two reformers arranged in parallel flow configuration, with the first reformer being a conventional reformer comprising a catalyst selective for reforming C8+ hydrocarbons to a reformate and the second reformer comprising a catalyst selective for reforming C7− hydrocarbons to a reformate. In certain embodiments, the first reformer catalyst comprises a conventional alumina catalyst and the second reformer catalyst comprises a ZSM-5 catalyst.
