ely meet the FCC gasoline hydro-upgrading requirements by single octane
recovery process or octane recovery-selective hydrodesulfurization combination process. However,
single selective hydrodesulfurization process or selective hydrodesulfurization-octane recovery
combination process can meet hydro-upgrading requirements for both the full range FCC gasoline and
heavy cut. The modified products with lower sulfur or clean gasoline of National Ⅳ standard can be
obtained by hydro-upgrading of FCC gasoline heavy cut.
Key words:selective hydrodesulfurization;octane recovery;FCC gasoline;hydro-upgrading
