Process for the production of propylene from a feed comprising olefins containing four and/or five carbon atoms with co-production of desulphurized gasoline with a high octane number

摘要

For producing propylene and co-producing desulphurized gasoline with a high octane number from a catalytically cracked gasoline cut, and a steam cracking C4/C5 cut, conduct at least one one-step oligocracking stage, a selective hydrogenation stage for FCC gasoline and a hydrotreatment stage.
