A process for converting isobutane to propylene. The process including dehydrogenating isobutane to produce a mixed product stream comprising isobutane and isobutene, skeletal isomerizing the mixed product stream comprising isobutane and isobutene to convert isobutene to n-butenes including 1-butene and 2-butenes and to recover a skeletal isomerization reaction product comprising isobutane, isobutene, butadiene, 1-butene, and 2-butenes. The process further including fractionating the skeletal isomerization reaction product, isomerizing the 1-butene contained therein to 2-butenes, recovering an overhead fraction comprising isobutane, a side draw fraction comprising isobutane and isobutene, and a bottoms fraction comprising 2-butenes, and combining the bottoms fraction with ethylene and converting the ethylene and 2-butenes to produce a reaction effluent comprising propylene.
