The invention relates to a process for converting cycle oils produced in catalytic cracking reactions into light olefin and naphtha. More particularly, the invention relates to a process of hydroprocessing a catalytically cracked light cycle oil in order to form a hydroprocessed cycle oil containing a significant amount of tetralins. The hydroprocessed cycle oil is then re- cracked in an upstream zone of the primary FCC riser reactor.
L'invention concerne un procédé de transformation d'huiles de recyclage produites dans des réactions de craquage catalytique en oléfines légères ou en naphta. Plus particulièrement, l'invention concerne un procédé d'hydrocraquage d'huiles de recyclage légères soumises à un craquage catalytique, permettant d'obtenir une huile de recyclage hydrocraquée contenant une concentration importante de tétralines. Cette huile de recyclage hydrocraquée est alors craquée à nouveau dans une zone amont du réacteur à colonne montante de craquage catalytique en lit fluidisé primaire.
