Abstract:
1. A method for forming a low-metal biomass-derived pyrolysis oil, the method comprising the steps of: filtering a biomass-derived pyrolysis oil with a high flux rate filter arrangement having a filter pore diameter of about 50 μm or greater with a flux rate of about 200 L/m filtering the low-solids biomass-derived pyrolysis oil with a fine filter arrangement having a pore diameter of about 50 μm or less to form an ultralow-solids biomass-derived pyrolysis oil; and contacting the ultralow-solids biomass-derived pyrolysis oil with an ion-exchange resin to remove metal ions and form the low-metal biomass-derived pyrolysis oil.
