(54) Title: ALKYLATION OF REFINERY PENTENES WITH ISOBUTANE (57) : A process, comprising: providing an olefin feed comprising pentenes, butenes, and isopentane; and alkylating the olefin 0 iv feed with isobutane using acidic ionic liquid catalyst; wherein a yield of the isopentane in an alkylate gasoline product corresponds il• to less than 15 mol% of C5 olefins in the feed, and the alkylate gasoline has defined fmal boiling point and high RON. A process 0 7 r comprising: alkylating an olefm feed comprising pentenes and isopentane, with isobutane using acidic ionic liquid catalyst; wherein a ---- GC yield of the isopentane in the alkylate gasoline corresponds to less than 15 mol% of C5 olefins in the feed; and wherein an n-pentane , 1 product yield is low. An alkylate gasoline, comprising less than 0.1 wt% olefms and aromatics, less than 1.8 wt% C12+ hydrocarbons, and N greater than 60 wt% combined Cg and C9 hydrocarbons, wherein the trimethylpentane in the Cg hydrocarbons and the trimethyihexane _ in the C9 hydrocarbons are defined.
