Process for the production of low benzene gasoline

   
   

A process for the production of low benzene content gasoline is disclosed wherein a full boiling range naphtha is fractionated to produce a light naphtha, a medium naphtha and a heavy naphtha. The benzene is contained in the medium naphtha and this stream is subjected to hydrogenation to convert the benzene to cyclohexane which may be isomerized to improve the octane. The valuable olefins are removed in the light naphtha and the valuable heavier aromatics (toluene and xylenes) are removed in the heavy naphtha. In a preferred embodiment all of the reactions are carried out in distillation column reactors.
