ABSTRACT:
A hydrocarbon conversion process for the hydrogenation of olefinic hydrocarbons wherein the feed is fractionated into a C.sub.4 -C.sub.5 light fraction and a C.sub.6 -C.sub.8 heavy fraction, the heavy feed fraction is mixed with the makeup hydrogen stream and passed upward through a first catalyst bed, the effluent of the first reaction zone is admixed with the recycle hydrogen stream and a first portion of the light feed fraction and passed upward through a second catalyst bed. At least a portion of the liquid which has passed through the second catalyst bed is cooled and admixed with a second portion of the light feed fraction.
