Processes for the production of a gasoline blend. A Cportion of a naphtha stream is first isomerized to increase the branched, iso-paraffins, and then, the isomerized effluent is passed to a dehydrogenation reaction zone. In the dehydrogenation zone, the Csaturated hydrocarbons are convert to Colefins. The Colefins have a higher octane number than the Csaturated hydrocarbons, and the branched olefins have a higher octane number than the normal olefins. The Colefins can be blended in a gasoline pool. Cand Chydrocarbons can be isomerized and dehydrogenated as well, separately or with the Ccomponents.

Processes for increasing an octane value of a gasoline component

A process for production of gasoline comprising separating a naphtha feed in a naphtha splitter into a stream comprising i-C, a stream comprising Cand lighter boiling hydrocarbons, a Cstream comprising Chydrocarbons, and a heavy stream comprising Cand heavier hydrocarbons; isomerizing at least a portion of the stream comprising Cand lighter boiling hydrocarbons in a C-Cisomerization zone at isomerization conditions to form a C-Cisomerization effluent; dehydrogenating at least a portion of the stream comprising Chydrocarbons to form a Cdehydrogenation effluent comprising Colefins; reforming the heavy stream in a reforming zone under reforming conditions forming a reformate stream; and blending one or more of the stream comprising i-C, the C-Cisomerization effluent, the Cdehydrogenation effluent and the reformate stream to form a gasoline blend.

A process for regenerating catalyst particles is disclosed. The process includes the steps: (a) withdrawing a regeneration zone effluent comprising halogen from a regeneration zone, wherein the regeneration zone contains catalyst particles comprising halogen; (b) contacting a first portion of the regeneration zone effluent with adsorbent in a first adsorption zone, removing halogen from the first portion of the regeneration zone effluent, and withdrawing from the first adsorption zone a first adsorption zone effluent; (c) contacting the first adsorption zone effluent with a water removing material to create a first water-depleted stream; and (d) passing the first water-depleted stream to the regeneration zone. Other embodiments include different orders of the steps.

Methods and apparatuses are provided for isomerizing a hydrocarbon stream. The method includes isomerizing a hydrocarbon stream in a reactor to produce an intermediate isomerized stream. The intermediate isomerized stream is fractionated to produce an off gas stream and a heavy isomerized stream, where the off gas stream includes an off gas recycle stream. The off gas recycle stream is dried in an off gas dryer to produce a hydrogen recycle stream, where the off gas drier includes an off gas dryer membrane separating the off gas recycle stream from an off gas purge stream. The off dryer membrane includes a perfluorosulfonated ionomer. The hydrogen recycle stream is then fed into the reactor.

A process for regenerating a catalyst used in a reaction zone. In a regeneration zone, the catalyst may be cooled before passing into a chloride rich zone. The regeneration zone may also receive a heated ambient oxygen in a catalyst heating zone. The regeneration zone may also receive recovered chloride from a chloride recovering zone which removes and recovers chloride from regeneration gas taken from the regeneration zone. Heated ambient oxygen may also be introduced into a chlorination zone.

Embodiments of processes for producing propylene from paraffins are provided. The process comprises the steps of combining an effluent that comprises propylene and propane from a paraffin dehydrogenation reactor with an offgas stream that comprises propane to form a combined effluent stream. The combined effluent stream is separated into a propylene product stream and a propane-rich recycle stream. The propane-rich recycle stream is introduced to the paraffin dehydrogenation reactor operating at dehydrogenation conditions to convert propane in the propane-rich recycle stream to propylene.

One exemplary embodiment is a process for oligomerizing one or more hydrocarbons. The process includes providing a feed including one or more C3 and C4 hydrocarbons to a separation zone, separating a first stream including an effective amount of C3 olefins for oligomerizing, separating a second stream including an effective amount of one or more C4 olefins for oligomerizing, providing at least a portion of the first stream to a first oligomerization zone for producing at least one of a C9 and a C12 hydrocarbon, and providing at least a portion of the second stream to a second oligomerization zone for producing at least one of a C8 and a C12 hydrocarbon.

A novel fractionation column (1) internal structure consists of groups of fractionation trays in which the upper trays rest upon the bottommost tray of the group, which is the only tray of the group supported by the column wall. Preferably the downcomers (13) or disengagement plates of the upper tray rest upon the tops of the downcomers (13) of the next lower tray. Only the bottom tray is supported as by a ring (12) attached to the column.
