Abstract:
Processes for reforming a hydrocarbon feedstock by selectively reforming different sub-components 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).

Claim (Index 1):
A process for reforming a hydrocarbon feedstock, comprising:\n a) providing a hydrocarbon feedstock comprising paraffins and naphthenes, each of which comprises from four to twelve carbon atoms, wherein the boiling point range of the hydrocarbon feedstock ranges from about \u221212\u00b0 C. to about 230\u00b0 C.; b) contacting the hydrocarbon feedstock with a first reforming catalyst at a temperature, a pressure and a hydrogen to hydrocarbon ratio that facilitates the catalytic aromatization of naphthenes in the hydrocarbon feedstock, thereby converting the hydrocarbon feedstock to a first reformer effluent characterized by an increased research octane number and increased wt. % of aromatics, wherein the contacting catalytically converts less than 50% of paraffins in the hydrocarbon feedstock; c) separating the first reformer effluent into a first fraction and a second fraction, wherein the first fraction is enriched in aromatics relative to the first reformer effluent and is suitable for use as a blend component of a liquid transportation fuel, and the second fraction is enriched in paraffins relative to the first reformer effluent; d) combining the second fraction with a second reforming catalyst at a temperature, a pressure and a hydrogen to hydrocarbon ratio that facilitates catalytic dehydrogenation of at least 50% of the paraffins in the second fraction by the second reforming catalyst, thereby producing a second reformer effluent that predominantly comprises olefins comprising four or five carbon atoms and unreacted paraffins and is characterized by an increased research octane number relative to the first reformer effluent.
