Abstract
Processes are provided for the production of butadiene from Ccontaining feed stocks that contain isobutene and/or isobutane in addition to n-butene(s) and/or n-butane. The processes of the present invention generally comprise feeding the feed stock to a combination butenes isomerization reaction and distillation tower for conversion of 1-butene to 2-butenes and separation from isobutene and isobutane, followed by an oxydehydrogenation unit to convert n-butenes to butadiene. The processes may also include additional isomerization and/or dehydrogenation steps for the tower overhead and bottoms streams to create additional isobutene and/or n-butenes for valued uses, which may include additional production of butadiene. The feed to the system may comprise any mixture or separate feeding of Colefins and Cparaffins, at least one of which contains isobutene and/or isobutane.
