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: Process for reforming a hydrocarbon feedstock comprising paraffins and naphthenes. A hydrocarbon feedstock is contacted with a first reforming catalyst in a first reactor at a temperature and pressure that facilitates conversion of naphthenes to aromatics while converting less than 50 wt. % of paraffins in the feedstock to olefins, thereby producing a first effluent that is separated into a first fraction that is enriched in aromatics and a second fraction that is enriched in paraffins. 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: 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).

Abstract: A process is disclosed for polishing a relatively highly pure stream of aromatic material bound for use as a petrochemical feedstock wherein the stream includes olefins and especially concerning, diolefins. The process comprises hydrotreating the highly pure aromatic stream with an unsulfided cobalt molybdenum catalyst that has low saturating activity for the aromatic but is active for saturating olefins and diolefins.

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.
