Abstract
Methods and systems for alkylate production involving a multi-zone alkylation reactor. The multi-zone alkylation reactor includes a plurality of alkylation zones spaced vertically in a series configuration and a partition splitting the plurality of alkylation zones into at least two mechanically separated catalytic volumes.
Claims20
An alkylation system comprising:
- a multi-zone alkylation reactor comprising:
- a plurality of alkylation zones spaced vertically in a series configuration;
- at least one vertical partition splitting the plurality of alkylation zones into at least a first mechanically separated catalytic volume and a second mechanically separated catalytic volume;
- an isobutane inlet positioned to supply an isobutane stream to the first mechanically separated catalytic volume;
- at least one olefinic feed inlet positioned to supply an olefin-containing stream to the plurality of alkylation zones, the olefin-containing stream reacting with the isobutane stream to produce an alkylate stream;
- and
- a first alkylate product conduit to transport the alkylate stream from the first mechanically separated catalytic volume to the second mechanically separated catalytic volume.

A method for production of an alkylate, the method comprising:
- supplying an isobutane stream to a multi-zone alkylation reactor, the multi-zone alkylation reactor having at least one vertical partition defining:
- a first mechanically separated catalytic volume comprising a first plurality of alkylation zones, and a second mechanically separated catalytic volume comprising a second plurality of alkylation zones;
- supplying an olefin-containing stream through at least one olefinic feed inlet to the first plurality of alkylation zones and the second plurality of alkylation zones to produce an alkylate stream;
- and
- directing the alkylate stream from the first plurality of alkylation zones through a first alkylate product conduit to the second plurality of alkylation zones.

A method for regenerating an alkylation zone of a multi-zone alkylation reactor, the method comprising:
- supplying a regeneration feed stream to an inlet of a multi-zone alkylation reactor, the multi-zone alkylation reactor having a vertical partition defining:
- a first mechanically separated catalytic volume comprising a first plurality of alkylation zones, and
- a second mechanically separated catalytic volume comprising a second plurality of alkylation zones;
- directing the regeneration feed stream through the first mechanically separated catalytic volume and through the second mechanically separated catalytic volume to regenerate spent alkylation catalyst therein by producing a regenerated catalyst having substantially increased alkylation activity and a spent regeneration stream;
- and
- directing the spent regeneration stream out of an outlet of the multi-zone alkylation reactor.
