A process for the treatment of a light naphtha feedstock that comprises normal paraffins and iso-paraffins may include separating the feedstock into a first iso-paraffin stream and a normal paraffin stream. The separating may be performed with 5A molecular sieves, a pressure of about 1-3 bars, and a temperature of 100-260° C. A product stream may be provided by subjecting the normal paraffin stream to at least one of steam cracking, isomerizing, and aromatizing.

Improved catalytic reforming processes and systems employ reforming reactors in a more efficient manner and can avoid problems associated with yield loss. Aromatics and isoparaffins are separated prior to passing to a reforming unit. An integrated process for producing gasoline blending components includes: separating a naphtha feedstream into an aromatic-rich stream and an aromatic-lean stream; separating the aromatic-lean stream into an isoparaffin-rich stream and an isoparaffin-lean stream; and catalytically reforming the isoparaffin-lean stream to produce a reformate stream.

A process increases the concentration of normal paraffins in a feed stream comprising separating a naphtha feed stream into a normal paraffin rich stream and a non-normal paraffin rich stream. The non-normal paraffin rich stream is isomerized over a first isomerization catalyst to convert non-normal paraffins to normal paraffins and produce a first isomerization effluent stream. An iso-C4 stream is separated from the first isomerization effluent stream and isomerized over a second isomerization catalyst to convert iso-C4 hydrocarbons to normal C4 hydrocarbons and produce a second isomerization effluent stream. The normal paraffin rich stream, the normal paraffins in the first isomerization effluent stream and/or the second isomerization effluent stream may be fed to a steam cracker.
