A reforming reactor and process of using same in which residence time of feed within a chamber of a reactor is shortened. Feed is injected into the reactor into a non-reactive zone. The non-reactive zone has two portions, a first portion receiving the feed, and a second portion receiving a purge gas. The purge gas will flow from the second portion to the first portion to prevent flow of the feed from the first portion to the second portion. The combined gas may be passed to a reaction zone for catalytic reforming. The first portion and the second portion may be separated by a baffle.

A process and a system for reforming and upgrading a heavy naphtha feedstock may include dehydrogenating naphthenes in the heavy naphtha feedstock to form a first effluent stream comprising aromatics and then separating the aromatics via extraction from the produced first effluent stream to produce a second effluent stream containing raffinate paraffins. The process may then include subjecting the second effluent stream to cyclization reactions to produce a third effluent stream comprising aromatics and then combining the first effluent stream and the third effluent stream prior to extraction

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.

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.

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).
