摘要： A process for catalytically treating a feed stream containing at least one organic compound is provided, which includes providing a distillative reaction system having a reaction section positioned at a top portion of the distillative reaction system and a reboiler and/or gas stripping section for vaporizing at least a portion of a bottom stream and returning the vaporized portion of the bottom stream to a bottom portion of the distillative reaction system, introducing an organic feed stream into the distillative reaction system below the uppermost reaction section, optionally introducing a gaseous reactant feed stream into the distillative reaction system below the uppermost reaction section, and removing an overhead product stream from a portion of the distillative reaction system above the uppermost reaction section without substantial reflux or recycling of the overhead product stream or feeding any other liquid stream that might recycle the desired products or any other compounds that are undesired to be refluxed, into the uppermost reaction section.

摘要： 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.摘要翻译： 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。
