PYROLYSIS OIL TREATMENT PROCESS INCLUDING PREFRACTIONATION

Abstract

Process of processing a feed comprising a pyrolysis oil of plastic and / or tires and / or solid recovered fuels (1), said process comprising the following steps: a) a pre-fractionation step of the feed to obtain a cut having a boiling point less than or equal to 120 °C (2) and a cut having a boiling point greater than 120 °C (3) containing olefins having 9 or more carbon atoms, b) a fluidized bed catalytic cracking step carried out in a fluidized bed catalytic cracking reaction section fed by at least said cut having a boiling point greater than 120 °C (3) to produce propylene (5).
