1. A method for upgrading a naphtha feed, the method comprising:
passing the naphtha feed to an adsorption unit to produce at least a paraffins stream and an isoparaffins stream, wherein the isoparaffin stream comprises isoparaffins and aromatics; and
passing the isoparaffins stream to an isoparaffin aromatization catalytic unit that contacts the isoparaffins stream with at least one aromatization catalyst to produce aromatics from the isoparaffins thereby yielding an aromatization effluent, wherein the at least one aromatization catalyst comprises ZSM-5 zeolite.
