Process and apparatus for selectively hydrogenating naphtha

The process and apparatus of the present invention selectively hydrogenates a heavier olefinic naphtha stream in an upstream catalyst bed and the hydrogenated effluent and a lighter olefinic naphtha stream in a downstream catalyst bed. The heavier di-alkenes are less re-active and are contacted with...

Zusammenfassung:The process and apparatus of the present invention selectively hydrogenates a heavier olefinic naphtha stream in an upstream catalyst bed and the hydrogenated effluent and a lighter olefinic naphtha stream in a downstream catalyst bed. The heavier di-alkenes are less re-active and are contacted with more hydrogenation catalyst than the lighter di-alkenes which are more re-active.
