Abstract: In recycling synthetic waste in a steam cracker, the waste is melted under inert conditions, and converted to prods. at 370-550 degrees C. A distillate fraction is sepd. from the prods. at 150-280 degrees C and fed to a steam cracker as feed.

Abstract: In a process for the recovery of a polymerizable useful fraction, consisting of styrene, methylstyrenes, vinyltoluenes, indene, methylindenes and fractions whose boiling points are between styrene and methylindenes, from the crack gases of a steam cracker, the sidestream of the crack gas column is divided, by means of a distillation unit, into the useful fraction and into fractions which are recycled to the crack gas column.
