Abstract
An integrated process for production of gasoline has been described. The process includes a C-Cisomerization zone, two Cisomerization zones separate by a deisoheptanizer, and a reforming zone. The use of two Cisomerization zones eliminates the need for the large recycle stream from the deisoheptanizer. The low temperature in first Cisomerization zone favors the formation of multi-branched Cparaffins and cyclohexanes and maximizes Cyield. The separation between paraffin and cycloalkane in deisoheptanizer becomes easier due to conversion of cycloalkanes to cyclohexanes in the first Cisomerization zone. Further, the high temperature in second Cisomerization zone favors the formation of higher octane cyclopentanes over cyclohexanes. An aromatic-containing stream can be introduced to second Cisomerization zone. The saturation of the aromatics in the second Cisomerization zone provides heat that increases the reactor outlet temperature in the isomerization reactors to favor cyclopentanes.
