Process for purifying pyrolysis oil

The present invention relates to a process for purifying a pyrolysis oil, the process comprising providing a stream S0 comprising a 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 depleted in the one or more organic compounds comprising conjugated double bonds as compared to S0; the stream S1 is subjected to dehalogenation in at least one dehalogenation zone Z2 downstream of Z1, obtaining a stream S2 depleted in the one or more halogenated organic compounds compared to S1. 本发明涉及一种用于纯化热解油的方法，该方法包括提供包含热解油的流S0，该热解油包含一种或多种卤化有机化合物和一种或多种包含共轭双键的有机化合物；使该流S0在至少一个含有非均相氢化催化剂的反应区Z1中经受氢化，获得与S0相比贫含该一种或多种包含共轭双键的有机化合物的流S1；使该流S1在Z1下游的至少一个脱卤区Z2中经受脱卤，获得与S1相比贫含该一种或多种卤化有机化合物的流S2。
