Abstract:
1. A process for the alkylation of isobutane with an olefin comprising: (a) feeding a first stream comprising an FCC hydrocarbon stream comprising an olefin to an oligomerization reactor, wherein at least a portion of the olefins react with each other to produce an effluent containing olefin oligomers; (b) fractionally distilling the effluent from the oligomerization reactor wherein unreacted C (c) feeding the first bottoms and a second stream containing isobutane to a first alkylation system where a portion of the isobutane is reacted with a portion of the olefin oligomers to form an effluent comprising a dilute alkylate stream; (d) feeding the effluent from the first alkylation system to a debutanizer where C (e) feeding the first overheads and the second overheads to a second alkylation system where isobutane is reacted with C
