Claim 8:
9. The alkylation system of claim 8, comprising the recirculation pump, wherein the recirculation pump is configured to:
receive the alkylate stream from the second alkylate product conduit;
direct a first portion of the alkylate stream for further processing to produce an enriched alkylate product containing high-octane, branched-chain paraffinic hydrocarbons; and
recirculate a second portion of the alkylate stream to the first mechanically separated catalytic volume, thereby maintaining a ratio of isobutane to olefin in the multi-zone alkylation reactor ranging from about 300:1 to about 500:1.
