Abstract
Improved catalytic reforming processes and systems employ reforming reactors in a more efficient manner and can avoid problems associated with yield loss. Aromatics and isoparaffins are separated prior to passing to a reforming unit. An integrated process for producing gasoline blending components includes: separating a naphtha feedstream into an aromatic-rich stream and an aromatic-lean stream; separating the aromatic-lean stream into an isoparaffin-rich stream and an isoparaffin-lean stream; and catalytically reforming the isoparaffin-lean stream to produce a reformate stream.
Claims19
An integrated process for producing gasoline blending components comprising:
- separating a naphtha feedstream into an aromatic-rich stream and an aromatic-lean stream;
- separating the aromatic-lean stream into an isoparaffin-rich stream and an isoparaffin-lean stream;
- and
- catalytically reforming the isoparaffin-lean stream by dehydrogenation of naphthenes to aromatics, isomerization of n-paraffins to iso-paraffins, and dehydrocyclization of paraffins to aromatics, to produce a reformate stream.
An integrated system for producing gasoline blending components comprising:
- a first separation zone operable to separate a naphtha feedstream into an aromatic-rich stream and an aromatic-lean stream, the first separation zone comprising one or more feed inlets in fluid communication with a source of the naphtha feedstream, one or more first outlets for discharging the aromatic-rich stream, one or more second outlets for discharging the aromatic-lean stream;
- a second separation zone operable to separate the aromatic-lean stream into an isoparaffin-rich stream and an isoparaffin-lean stream, the second separation zone comprising one or more inlets in fluid communication with the second outlet of the first separation zone, one or more first outlets for discharging the isoparaffin-rich stream, and one or more second outlets for discharging the isoparaffin-lean stream;
- and
- a catalytic reforming zone operable to produce a reformate comprising at least one inlet in fluid communication with the second outlet of the second separation zone;
- and at least one outlet for discharging reformate, said catalytic reforming zone selected from a semi-regenerative unit, a cyclic regeneration unit, and a continuous catalyst regeneration unit.
