Claim 19:
20. A system comprising:
a naphthene conversion unit comprising a ring opening catalyst, the naphthene conversion unit operable to convert naphthenes from a naphtha feed to produce a converted effluent comprising a mixture of isoparaffins and n-paraffins;
a reverse isomerization unit disposed downstream of the naphthene conversion unit, the reverse isomerization unit comprising an isomerization catalyst and operable to convert isoparaffins from at least one isoparaffin rich stream to n-paraffins to produce an isomerate comprising a concentration of n-paraffins greater than a concentration of n-paraffins in the at least one isoparaffin-rich stream;
a paraffin separation system operable to separate at least a portion of the converted effluent and at least a portion of the isomerate to produce the at least one isoparaffin-rich stream and at least one n-paraffin-rich stream; and
a steam cracker disposed downstream of the paraffin separation system and operable to steam crack the at least one n-paraffin-rich stream to produce a cracker effluent comprising at least ethylene.
