    • Processes are provided for the production of butadiene from C
      4 containing feed stocks that contain isobutene and/or isobutane in addition to n-butcne(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 I -butene to 2-butenes and separation from isobutene and isobutane, followed by an oxydchydrogenation 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-bulenes for valued uses, which may include additional production of butadiene. The feed to the system may comprise any mixture or separate feeding of C
      4 olefins and C
      4 paraffins, at least one of which contains isobutene and/or isobutane.
    • 提供用于从包含异丁烯和/或异丁烷以及正丁烷和/或正丁烷的含C4原料的原料生产丁二烯的方法。 本发明的方法通常包括将原料进料到组合丁烯异构化反应和用于将1-丁烯转化为2-丁烯的蒸馏塔,并从异丁烯和异丁烷中分离出来,随后用氧化脱氢单元将正丁烯转化为丁二烯 。 该方法还可以包括用于塔塔顶馏出物和塔底物流的另外的异构化和/或脱氢步骤以产生用于重要用途的额外的异丁烯和/或正丁烯,其可以包括额外生产丁二烯。 系统的进料可以包括C4烯烃和C4链烷烃的任何混合物或单独进料,其中至少一种含有异丁烯和/或异丁烷。
