Decontamination of deoxygenated biomass-derived pyrolysis oil using ionic liquids |
摘要 |
Embodiments of methods for purifying a biomass-derived pyrolysis oil are provided. The method comprises the step of contacting the biomass-derived pyrolysis oil with a first deoxygenating catalyst in the presence of hydrogen at first predetermined hydroprocessing conditions to form a first low-oxygen biomass-derived pyrolysis oil effluent. The low-oxygen biomass-derived pyrolysis oil effluent is contacted with an ionic liquid to remove phenolic compounds, nitrogen compounds and other impurities. This ionic liquid step may be followed by a second deoxygenation step or the deoxygenating may be completed and then followed by the ionic liquid purification step. |

1. A method for purifying a biomass-derived pyrolysis oil, the method comprising the steps of:
contacting the biomass-derived pyrolysis oil with a first deoxygenating catalyst in the presence of hydrogen at first predetermined hydroprocessing conditions to form a first low-oxygen biomass-derived pyrolysis oil effluent; and contacting the first low-oxygen biomass-derived pyrolysis oil effluent with an ionic liquid to remove impurities from said first low-oxygen biomass-derived pyrolysis oil effluent wherein said impurities consist of at least one nitrogen compound or one phenolic compound. |
