Recovery of 1-butene from c.sub.4-hydrocarbon mixtures containing 2-butenes |
| abstract |
Abstract of the Disclosure: 1-Butene is recovered from a C4-hydrocarbon mixture which contains 2-butenes and may or may not contain 1-butene by catalytic isomerization of the 2-butenes to 1-butene at elevated temperatures and iso-lation of the 1-butene, by a process in which the said iso-merization is carried out in the presence of an acidic catalyst at from 150 to 500°C, the isomerization mixture obtained from the isomerization zone is fed into a dis-tillation zone, 1-butene is taken off at the top of the distillation zone, a fraction containing 2-butenes is taken off in the lower third of the distillation zone and fed into the isomerization zone, and the starting C4-hydrocarbon mixture which contains 2-butenes and may or may not contain 1-butene is fed to the distillation zone and/or the isomerization zone. |
