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.

Claim (Index 1):
A system for reforming a hydrocarbon feedstock, comprising:\n a) A separation unit operable to receive and separate a hydrocarbon feedstock comprising paraffins and naphthenes containing from four to twelve carbon atoms into a first fraction that comprises an increased percentage (by weight) of naphthenes relative to the hydrocarbon feedstock, and a second fraction that comprises an increased percentage (by weight) of paraffins content relative to the hydrocarbon feedstock, wherein the hydrocarbon feedstock is characterized by a boiling point range from about \u221212\u00b0 C. to about 230\u00b0 C.; b) A first reforming unit that contains a first reforming catalyst comprising a solid support that comprises acidic sites,\n wherein the first reforming unit is operable to receive the first fraction and to facilitate contact between the first fraction and the first reforming catalyst to convert the first fraction to a first reformer effluent that comprises an increased wt. % of aromatics relative to the first fraction and is characterized by an increased research octane number, \n wherein the first reforming unit is operable to maintain conditions comprising a temperature of 480\u00b0 C. or less, a pressure and a hydrogen to hydrocarbon ratio that are suitable to facilitate the catalytic conversion of naphthenes present in the first fraction by the first reforming catalyst while minimizing cracking of naphthenes present in the first fraction and aromatics present in the first reformer effluent; \n c) A second reforming unit that contains a second reforming catalyst comprising a solid support, that does not comprise acidic sites,\n wherein the second reforming unit is operable to receive the second fraction and to combine the second fraction with the second reforming catalyst to produce a second reformer effluent, wherein the combining is conducted at a temperature, a pressure and a hydrogen to hydrocarbon ratio that facilitates the dehydrogenation of at least 50% of the paraffins present in the second fraction and convert residual naphthenes present in the second fraction to aromatics, wherein the second reformer effluent comprises predominantly olefins containing four or five carbon atoms, unreacted paraffins and residual aromatics, wherein the second reformer effluent is characterized by an increased research octane number relative to the second fraction.
