The present invention concerns a moving bed catalyst regenerator (1) comprising a vessel (2) extending in a vertical direction, said vessel being divided into at least two regeneration zones extending along the vertical height of said vessel, in which particles of catalyst move under gravity, in which each regeneration zone comprises, in succession and in the order in which the catalysts move: a) a combustion section (CO); b) an oxychlorination section (O) disposed below the combustion section and comprising means for bringing catalyst from the combustion section (CO) to the oxychlorination section (O); c) a calcining section (CA) disposed below the oxychlorination section; characterized in that the regeneration zones are separated from each other by a separation means which is impermeable to catalysts and to gases in a manner such that the catalysts of each of the zones are capable of being regenerated under different operating conditions.

Processes for catalytic reforming in which a cracking inhibitor, such as an olefin, or a light olefin, is used to inhibit thermal cracking of larger hydrocarbons in non-reactive zones. The cracking inhibitor may be added at various positions through the processes, such as in the recycle gas stream, before a heater, before a stream is passed into a reforming zone, after an effluent stream is recovered from a reforming zone. A molar ratio of cracking inhibitor to hydrocarbons in stream may be between 0.01 and 0.2.

Processes and apparatuses for producing aromatic compounds from a naphtha feed stream are provided herein. In an embodiment, a process for producing aromatic compounds includes heating the naphtha feed stream to produce a heated naphtha feed stream. The heated naphtha feed stream is reformed within a plurality of reforming stages that are arranged in series to produce a downstream product stream. The plurality of reforming stages is operated at ascending reaction temperatures. The naphtha feed stream is heated by transferring heat from the downstream product stream to the naphtha feed stream to produce the heated naphtha feed stream and a cooled downstream product stream.

The present invention relates to methods and systems useful for producing aromatics-rich products from liquid hydrocarbon condensates. The production system includes a hydroprocessing reactor, an aromatization reactor system and a hydrogen extraction unit. The methods for producing the aromatics-rich products include introducing a wide boiling range condensate into the hydroprocessing reactor and operating the aromatics production system such that the hydroprocessing reactor forms a naphtha boiling temperature range liquid product. The liquid hydrocarbons produced in accordance with the present invention may optionally be further processed using a hydrogen extraction unit to produce a high-purity hydrogen fraction.

A fixed bed, radial flow reforming reactor having an inner catalyst zone between an inlet fluid zone and an outlet fluid zone. The catalyst zone is separated into two concentric, annular zones, a first annular zone having a first solid particle material having a first catalytic activity for reforming hydrocarbons into the catalyst zone, and, a second annular zone having a second solid particle material having a second catalytic activity for reforming hydrocarbons into the catalyst zone, wherein the second catalytic activity is different. One of the materials may be inert. A divider may be used to separate the two annular zones.
