Abstract
Improved processes for production of gasoline with 95 RONC including a C-Cisomerization zone, two Cisomerization zones, and a reforming zone are described. The first and second Cisomerization zones share a common stabilizer which strips off the chlorides and removes the light ends. The capital and operating costs of the processes are reduced through the elimination of one of the stabilizer columns and the associated condenser, receiver, trim cooler, and reboiler. The processes improve the RONC of the Cisomerization product because unconverted methylcyclohexane is recycled back to the second Cisomerization zone to be converted into dimethylcyclopentane.
