摘要： A process to produce olefins including: (a) Providing a hydrocarbon stream containing at least 10 wt % of pyrolysis plastic oil; (b) Optionally contacting the effluent obtained in step a) 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 containing lamellar double hydroxide modified or not and silica gel, or any mixture thereof; (c) performing a selective hydrogenation step; (d) contacting the stream obtained in step c) with a cracking catalyst to crack the olefins and/or paraffins into olefins having 2 to 4 carbon atoms (e) separating from the effluents obtained at the step d) a first stream containing olefins and saturated hydrocarbons having at most 3 carbon atoms, and a second stream containing hydrocarbons having 4 or more carbon atoms and (f) recovering from said first stream the ethylene and propylene.

摘要： 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.
