ABSTRACT:
A process is provided to react a feedstock comprising isobutane with pentenes in the presence of sulfuric acid catalyst to produce a high octane alkylate as well as a higher octane isopentane gasoline blending component. A method to reduce sulfuric acid consumption during alkylation is provided wherein a diolefinic contaminant of a pentene system feed is selectively hydrogenated before alkylation. An alkylation method is provided wherein the alkylation feed is separated into a fraction comprising substantially C.sub.4 and lower olefins and a fraction comprising substantially C.sub.5 olefins and the stream comprising C.sub.5 olefins is alkylated in a different reactor than the fraction comprising substantially C.sub.4 and lower olefins.
