METHODS FOR DEOXYGENATING BIOMASS-DERIVED PYROLYSIS OILS

摘要

METHODS (10) FOR DEOXYGENATING TREATED BIOMASS-DERIVED PYROLYSIS OIL (90) ARE PROVIDED. THE TREATED BIOMASS-DERIVED PYROLYSIS OIL IS EXPOSED TO A CATALYST HAVING A NEUTRAL CATALYST SUPPORT SUCH AS A NON-ALUMINA METAL OXIDE SUPPORT, A THETA ALUMINA SUPPORT, OR BOTH. THE NON-ALUMINA METAL OXIDE SUPPORT MAY BE A TITANIUM OXIDE (TiO₂) SUPPORT, A SILICON OXIDE SUPPORT, A ZIRCONIA OXIDE (ZrO₂) SUPPORT, A NIOBIUM OXIDE (Nb₂O₅) SUPPORT, OR A SUPPORT HAVING A MIXTURE OF NON-ALUMINA METAL OXIDES. THE CATALYST MAY INCLUDE A NOBLE METAL OR A GROUP VIII NON-NOBLE METAL AND A GROUP VIB NON-NOBLE METAL ON THE NEUTRAL CATALYST SUPPORT. THE TREATED BIOMASS-DERIVED PYROLYSIS OIL IS INTRODUCED INTO A HYDROPROCESSING REACTOR IN THE PRESENCE OF THE CATALYST UNDER HYDROPROCESSING CONDITIONS TO PRODUCE LOW OXYGEN BIOMASS-DERIVED PYROLYSIS OIL (120). THE MOST ILLUSTRATIVE DRAWING IS FIG.2.
