Claim 17:
18. 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.
