Systems for reforming a feedstock comprising paraffins and naphthenes. A first reactor containing a first reforming catalyst is operable to maintain a temperature and pressure that facilitates conversion of naphthenes in the feedstock to aromatics while facilitating conversion of less than 50 wt. % of paraffins in the feedstock to olefins. A first separator receives and separates the first effluent that is produced in the first reactor to produce a first fraction enriched in aromatics and a second fraction enriched in paraffins. A second reactor containing a second reforming catalyst is operable to maintain a temperature and pressure that facilitates conversion of at least 50 wt. % of paraffins in the second fraction to olefins. The system is operable to produce a liquid hydrocarbon product suitable for use as a blend component of a liquid transportation fuel.
