摘要： 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.

摘要： 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.

摘要： 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.
