Abstract: The present invention relates to a process for purifying a pyrolysis oil comprising providing a stream S0 comprising a pyrolysis oil, the pyrolysis oil comprising one or more halogenated organic compounds and one or more organic compounds comprising conjugated double bonds; subjecting the stream S0 to hydrogenation in at least one reaction zone Z1 containing a heterogeneous hydrogenation catalyst, obtaining a stream S1 being depleted, compared to S0, in the one or more organic compounds comprising conjugated double bonds; subjecting the stream S1 to dehalogenation in at least one dehalogenation zone Z2 down-stream of Z1, obtaining a stream S2 being depleted, compared to S1, in the one or more halogenated organic compounds.

Abstract: A process for purifying a pyrolysis oil originating from pyrolysis of plastic waste is provided, wherein the process comprises a dehalogenation of the pyrolysis oil, wherein the dehalogenation comprises contacting the pyrolysis oil with one or more adsorption materials and/or subjecting the pyrolysis oil to a temperature of about 280° C. or more, wherein a halogen content of a resulting purified pyrolysis oil is about 55% or more lower compared to the halogen content of the untreated pyrolysis oil.
