Abstract: 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.

Abstract: Process for reforming a hydrocarbon feedstock comprising paraffins and naphthenes. A hydrocarbon feedstock is separated to produce a first fraction enriched in naphthenes and a second fraction that is enriched in paraffins. The first fraction is contacted with a first reforming catalyst in a first reactor that is maintained at a temperature and pressure that facilitates conversion of naphthenes to aromatics. The second fraction is contacted with a second reforming catalyst in a second reactor at a temperature and pressure that converts at least 50 wt. % of paraffins in the second fraction to olefins. The process produces a liquid hydrocarbon reformate product suitable for use as a blend component of a liquid transportation fuel.

Abstract: Systems for reforming a hydrocarbon feedstock, where the system is operable to selectively reform different sub-components of the hydrocarbon feedstock using at least two structurally-distinct reforming catalysts. Advantages may include a decreased rate of reforming catalyst deactivation and an increased yield of a liquid hydrocarbon reformate product that is characterized by at least one of an increased octane rating and a decreased vapor pressure compared to the liquid hydrocarbon reformate product of conventional one-step reforming systems.

Abstract: Processes for reforming a hydrocarbon feedstock by selectively reforming different sub-components or fractions of the feedstock using at least two compositionally-distinct reforming catalysts. Advantages may include a decreased rate of reforming catalyst deactivation and an increased yield of a liquid hydrocarbon reformate product that is characterized by at least one of an increased octane rating and a decreased vapor pressure (relative to conventional one-step reforming processes and systems).
