Abstract: Processes for the production of a gasoline blend. A C7 portion of a naphtha stream is first isomerized to increase the branched, iso-paraffins, and then, the isomerized effluent is passed to a dehydrogenation reaction zone. In the dehydrogenation zone, the C7 saturated hydrocarbons are convert to C7 olefins. The C7 olefins have a higher octane number than the C7 saturated hydrocarbons, and the branched olefins have a higher octane number than the normal olefins. The C7 olefins can be blended in a gasoline pool. C5 and C6 hydrocarbons can be isomerized and dehydrogenated as well, separately or with the C7 components.

Abstract: A process for production of gasoline comprising separating a naphtha feed in a naphtha splitter into a stream comprising i-C5, a stream comprising C6 and lighter boiling hydrocarbons, a C7 stream comprising C7 hydrocarbons, and a heavy stream comprising C8 and heavier hydrocarbons; isomerizing at least a portion of the stream comprising C6 and lighter boiling hydrocarbons in a C5-C6 isomerization zone at isomerization conditions to form a C5-C6 isomerization effluent; dehydrogenating at least a portion of the stream comprising C7 hydrocarbons to form a C7 dehydrogenation effluent comprising C7 olefins; reforming the heavy stream in a reforming zone under reforming conditions forming a reformate stream; and blending one or more of the stream comprising i-C5, the C5-C6 isomerization effluent, the C7 dehydrogenation effluent and the reformate stream to form a gasoline blend.

Abstract: Embodiments of processes for producing propylene from paraffins are provided. The process comprises the steps of combining an effluent that comprises propylene and propane from a paraffin dehydrogenation reactor with an offgas stream that comprises propane to form a combined effluent stream. The combined effluent stream is separated into a propylene product stream and a propane-rich recycle stream. The propane-rich recycle stream is introduced to the paraffin dehydrogenation reactor operating at dehydrogenation conditions to convert propane in the propane-rich recycle stream to propylene.

Abstract: One exemplary embodiment is a process for oligomerizing one or more hydrocarbons. The process includes providing a feed including one or more C3 and C4 hydrocarbons to a separation zone, separating a first stream including an effective amount of C3 olefins for oligomerizing, separating a second stream including an effective amount of one or more C4 olefins for oligomerizing, providing at least a portion of the first stream to a first oligomerization zone for producing at least one of a C9 and a C12 hydrocarbon, and providing at least a portion of the second stream to a second oligomerization zone for producing at least one of a C8 and a C12 hydrocarbon.

Abstract: Methods of and apparatuses for separating a linear hexane stream from a hydrocarbon feed that includes unbranched C4 to C7 hydrocarbons are provided. In an embodiment, a method of separating a linear hexane stream from a hydrocarbon feed including unbranched C4 to C7 hydrocarbons includes isomerizing the hydrocarbon feed in the presence of hydrogen to produce an isomerized hydrocarbon stream that includes branched hydrocarbons and linear hexane. The isomerized hydrocarbon stream is separated into at least an isomerate product stream and a hexane-containing raffinate stream that includes linear hexane. The linear hexane stream is separated from at least a portion of the hexane-containing raffinate stream to produce the linear hexane stream and a hexane-depleted raffinate stream. The linear hexane stream is isolated as an independent product stream.

Abstract: One exemplary embodiment can be a process for separating at least one oligomerized effluent. The process can include providing an effluent from at least one of a first oligomerization zone for producing at least one of a C9 and a C12 hydrocarbon and a second oligomerization zone for producing at least one of a C8 and a C12 hydrocarbon, providing at least a portion of the effluent to a separation zone, and providing at least one stream from the separation zone to a hydrotreatment zone.

Abstract: One exemplary embodiment can be a process for oligomerizing one or more hydrocarbons. The process can include providing a feed including one or more C3 and C4 hydrocarbons to a separation zone, separating at least a portion of C3 olefins, sending the C3 olefins to a first oligomerization zone for producing one or more C9 hydrocarbons, and returning at least a portion of an effluent from the first oligomerization zone to the separation zone.
