Abstract
Unsaturated C.sub.4 hydrocarbons are converted into normal butane by introducing an unsaturated C.sub.4 hydrocarbon stream into a hydrogenation zone to convert it into a stream of normal butane and isobutane. Normal butane is recovered from a separation zone while isobutane is directed to an isomerization zone wherein a portion of the isobutane is converted into normal butane. The stream from the isomerization zone is returned to the separation zone to recover the normal butane produced in the isomerization reaction. The normal butane produced by the process is subsequently utilized in a cracking zone to produce ethylene.
