CYCLE OIL CONVERSION PROCESS

The invention relates to a process for converting cycle oils produced in catalytic cracking reactions into olefin and naphtha. More particularly, the invention relates to a process for hydroprocessing a catalytically cracked light cycle oil, and then re-cracking it in an upstream zone of the primary...

More Information
Summary:The invention relates to a process for converting cycle oils produced in catalytic cracking reactions into olefin and naphtha. More particularly, the invention relates to a process for hydroprocessing a catalytically cracked light cycle oil, and then re-cracking it in an upstream zone of the primary FCC riser reactor. L'invention concerne un procédé permettant de convertir en oléfine et en naphta des huiles recyclées obtenues pendant des réactions de craquage catalytique. D'une manière plus spécifique, l'invention concerne un procédé permettant d'hydrotraiter une huile recyclée légère soumise à un craquage catalytique, puis à la soumettre une nouvelle fois à un craquage dans une zone en amont du réacteur primaire à colonne montante de craquage catalytique fluide.
