A process for the purification of a hydrocarbon stream including: (a) Providing a hydrocarbon stream having a diene value of at least 1.0 and a bromine number of at least 5 gBr2/100and containing pyrolysis plastic oil; (b) Optionally contact the hydrocarbon stream obtained in step (a) with a silica gel, clays, alkaline or alkaline earth metal oxide, iron oxide, ion exchange resins, active carbon, active aluminum oxide, molecular sieves, alkaline oxide and/or porous supports and silica gel, or any mixture thereof, (c) Heating the stream obtained in step a) or b) followed by a mixing of the heated stream with a second diluent heated at a temperature of at least 300° C. preferably at least 330° C.; (d) performing an hydroprocessing step at a temperature of at least 250° C. in the presence of H2; and (e) recovering a purified hydrocarbon stream.

Purification of waste plastic based oil with a high temperature hydroprocessing

A process to produce olefins and aromatics via a purification of a hydrocarbon stream including: a) Providing a hydrocarbon stream having a starting boiling point of at least 15° C., a diene value of at least 1.0 preferably at least 1.5 g I2/100 g and a bromine number of at least 5 g Br2/100 g and containing at least 10 wt % of pyrolysis plastic oil where preferably at least 10 wt. % of said hydrocarbon stream has a boiling point of at least 150° C. based on the total weight of said hydrocarbon stream; c) Performing a first hydrotreating step; e) performing a second hydrotreating step; and f) recovering a purified hydrocarbon stream wherein at least a part of this purified hydrocarbon stream is sent to a steam cracker to produce olefins, such as ethylene and propylene, and aromatics.
