PROCESSES AND SYSTEMS FOR PETROCHEMICAL PRODUCTION INTEGRATING FLUID CATALYTIC CRACKING AND DEEP HYDROGENATION OF FLUID CATALYTIC CRACKING REACTION PRODUCTS

摘要

A feedstock is processed in an FCC unit to produce at least light olefins, FCC naphtha, light cycle oil and heavy cycle oil. Light cycle oil, and in certain embodiments hydrotreated light cycle oil, is subjected to deep hydrogenation to produce a deeply hydrogenated middle distillate fraction. All or a portion of the deeply hydrogenated middle distillate fraction is used as feed to the stream cracking zone to produce light olefins.
