Abstract:
Methods are provided for producing bio-oil polyols, alkoxylating bio-oil polyols to provide polyols, and for employing the alkoxylated bio-oil polyols for making polymers or copolymers of polyesters or polyurethanes. Compositions and methods are provided for incorporating bio-oils into phenolic resins such as phenol-formaldehyde resin and phenol- formaldehyde -urea resin, as well as hot melt adhesive compositions.
Abstract:
Described are methods and systems for preparing stabilized bio-oil suitable for subsequent hydrotreatment and forming a hydrocarbon product from a stabilized bio-oil. For example, preparing stabilized bio-oil suitable for subsequent hydrotreatment may include filtering bio-oil effective to remove at least a portion of particles having an effective particulate diameter greater than about 10 micrometers; treating the bio-oil effective to remove at least a portion of inorganic species from the bio-oil; and catalytically stabilizing the bio-oil to provide the stabilized bio-oil suitable for subsequent hydrotreatment. Forming a hydrocarbon product from a stabilized bio-oil may include hydrotreating the stabilized bio-oil by, for example, contacting the stabilized bio-oil to a hydrotreatment catalyst in the presence of hydrogen, thereby providing the hydrocarbon product. Also included are stabilized bio-oil and hydrocarbon products derived therefrom.
