ABSTRACT:
In a process for the thermal cracking of hydrocarbons to produce olefins, improvement of recovering hydrocarbons boiling above 200.degree. C. from the thermal cracking stage, preferably removing polymeric components therefrom, catalytically hydrogenating resultant hydrocarbons boiling above 200.degree. C., and recycling resultant hydrogenated hydrocarbons to the thermal cracking stage.
