Abstract
Embodiments of methods and apparatuses for forming a low-metal biomass-derived pyrolysis oil are provided. The method comprises the steps of filtering a biomass-derived pyrolysis oil with a high flux rate filter arrangement having a flux rate of about 10 L/m/hr or greater to form a low-solids biomass-derived pyrolysis oil. The low-solids biomass-derived pyrolysis oil is filtered with a fine filter arrangement having a pore diameter of about 50 μm or less to form an ultralow-solids biomass-derived pyrolysis oil. The ultralow-solids biomass-derived pyrolysis oil is contacted with an ion-exchange resin to remove metal ions and form the low-metal biomass-derived pyrolysis oil.
