Process for production of benzene lean gasoline by recovery of high purity benzene from unprocessed cracked gasoline fraction containing organic peroxides

摘要

Disclosed is a process for production of benzene lean gasoline by recovery of high purity benzene from a narrow boiling benzene concentrated unprocessed cracked gasoline fraction. The process involves subjecting the feed material to an extractive distillation (ED) operation using an aromatic selective solvent in combination with a co-solvent.
