Abstract: A process for purification a hydrocarbon stream including: (a) Providing a hydrocarbon stream having a diene value of at least 1.0, a bromine number of at least 5 g and containing at least 10 wt % of pyrolysis plastic oil; b) contacting the effluent obtained in step a) with a silica gel, clays, alkaline or alkaline earth metal oxide, iron oxide, ion exchange resins, active carbon, active aluminium oxide, molecular sieves, alkaline oxide and/or porous supports, and/or silica gel, or any mixture thereof; c) performing a first hydrotreating step; d) contacting the effluent obtained in step c) with silica gel, clays, alkaline or alkaline earth metal oxide, iron oxide, ion exchange resins, active carbon, active aluminium oxide, molecular sieves, alkaline oxide and/or porous supports and silica gel, or any mixture thereof; e) performing a second hydrotreating step; and f) recovering a purified hydrocarbon stream.

Abstract: 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 gBr2/100 g and 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.

Abstract: 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.
