The present invention discloses a process and apparatus for selectively hydrogenating diolefins in a cracked stream. The method combines a conversion unit and a recovery section. The recovery section includes the diolefin hydrogenation reactor that is used to selectively hydrogenate the diolefins in the cracked naphtha. The diolefin depleted naphtha may be debutanized to separate the stabilized naphtha and liquefied petroleum gas streams.
