ABSTRACT:
A naphtha feed is contacted in a penultimate aromatic forming stage under catalytic aromatic forming conditions with a first catalyst. The effluent from the penultimate stage is contacted in a final aromatic forming stage under catalytic aromatic forming conditions and at substantially the same pressure as is maintained in the penultimate stage with a second catalyst. The pressure is selected to provide optimal aromatic production per calendar day from the final stage.
