Abstract: Processes are provided for the production of butadiene from C4 containing 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 C4 olefins and C4 paraffins, at least one of which contains isobutene and/or isobutane.

Abstract: A process for the oxidative dehydrogenation of ethane is disclosed. The process may include: contacting an ethane feed and an oxygen-containing gas in the presence of an oxidative dehydrogenation catalyst in an oxidative dehydrogenation reaction zone under conditions to oxidatively dehydrogenate at least a portion of the ethane to produce a product stream comprising ethylene, carbon oxides, water, and unreacted oxygen and ethane, wherein an oxygen concentration in the product stream is at least 0.1 mol %; contacting the product stream with an oxygen elimination catalyst in an oxygen elimination reaction zone to combust at least a portion of the oxygen; recovering from the oxygen elimination reaction zone an effluent having a reduced oxygen content; separating water from the effluent; separating carbon oxides and any non-condensable gas(es) from the ethylene and the unreacted ethane; and separating the ethylene from the unreacted ethane.

Abstract: 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
