Abstract:
1. A process for the utilization of refinery C 4 streams in the production of gasoline comprising the steps of: (a) feeding hydrogen and a mixed C (b) concurrently in said first distillation column reactor, (c) removing said C (d) removing said normal butane, isobutane, 1-butene, 2-butene and isobutene from said first distillation column reactor as a first overheads; (e) feeding said first overheads containing said normal butane, isobutane, 1-butene, 2-butene and isobutene to a second distillation column reactor containing an bed of isomerization catalyst; (f) concurrently in said second distillation column reactor, (g) removing the 2-butene from said second distillation column reactor as a second bottoms; (h) removing the isobutane, unreacted 1-butene and isobutene from said second distillation column reactor as a second overheads; (i) feeding said hydrogen and second overheads containing said normal butane, isobutane, isobutene and 1-butene to a third distillation column reactor containing a bed of hydrogenation catalyst to concurrently; (j) removing the normal butane, isobutane, 1-butene an isobutene from said third distillation column reactor as a third bottoms.
