The present invention relates to a process for selectively producing C3 olefins from a catalytically cracked or thermally cracked naphtha stream by injecting a C6 rich fraction separated from the naphtha-boiling-range feedstream and/or the product stream into the cracking stage at a place downstream from the feed.
L'invention concerne un procédé de fabrication sélective d'oléfines C¿3? à partir d'un flux naphta à craquage catalytique ou thermique, par injection d'une fraction riche en C¿6?, séparée du flux de charge à point d'ébullition naphta, et/ou du flux de produit, au niveau de l'étage de craquage, en un point situé en aval de la charge.
