A process, comprising: providing an olefin feed comprising pentenes, butenes, and isopentane; and alkylating the olefin feed with isobutane using acidic ionic liquid catalyst; wherein a yield of the isopentane in an alkylate gasoline product corresponds to less than 15 mol% of C5 olefins in the feed, and the alkylate gasoline has defined final boiling point and high RON. A process comprising: alkylating an olefin feed comprising pentenes and isopentane, with isobutane using acidic ionic liquid catalyst; wherein a 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 product yield is low. An alkylate gasoline, comprising less than 0.1 wt% olefins and aromatics, less than 1.8 wt% C12+ hydrocarbons, and greater than 60 wt% combined C8 and C9 hydrocarbons, wherein the trimethylpentane in the C8 hydrocarbons and the trimethylhexane in the C9 hydrocarbons are defined. |
