| 摘要 |
The invention relates to a process for upgrading a pyrolysis oil comprising the following steps: hydrodeoxygenation treatment (10) of the pyrolysis oil (12) and separation of the effluent (16) obtained into a light aqueous fraction (18) and a heavy organic fraction (20), or separation of the pyrolysis oil into an aqueous fraction and a lignin-rich fraction, pre-reforming (22) of said aqueous fraction (18) and treatment of the effluent (26) obtained in an SMR unit (28) in N order to produce hydrogen (34), hydrotreatment (40) and/or catalytic cracking and/or visbreaking of said heavy organic fraction (20).
