摘要
(US9163181) Embodiments of methods and apparatuses for deoxygenating a biomass-derived pyrolysis oil are provided.  In one example, a method comprises the steps of separating a low-oxygen biomass-derived pyrolysis oil effluent into a low-oxygen-pyoil organic phase stream and an aqueous phase stream.  Phenolic compounds are removed from the aqueous phase stream to form a phenolic-rich diluent recycle stream.  A biomass-derived pyrolysis oil stream is diluted and heated with the phenolic-rich diluent recycle stream to form a heated diluted pyoil feed stream.  The heated diluted pyoil feed stream is contacted with a deoxygenating catalyst in the presence of hydrogen to deoxygenate the heated diluted pyoil feed stream.

(US9163181) What is claimed is: 1.  A method for deoxygenating a biomass-derived pyrolysis oil, the method comprising the steps of: separating a low-oxygen biomass-derived pyrolysis oil effluent comprising phenolic compounds into a low-oxygen-pyoil organic phase stream and an aqueous phase stream at first separation conditions in which phenolic compounds in the low-oxygen biomass-derived pyrolysis oil effluent are miscible in the aqueous phase stream;   removing the phenolic compounds from the aqueous phase stream at second separation conditions in which the phenolic compounds are immiscible in the aqueous phase stream to form a phenolic-rich diluent recycle stream;   diluting and heating a biomass-derived pyrolysis oil stream with the phenolic-rich diluent recycle stream to form a heated diluted pyoil feed stream; and   contacting the heated diluted pyoil feed stream with a deoxygenating catalyst in the presence of hydrogen at hydroprocessing conditions effective to deoxygenate the heated diluted pyoil feed stream to produce the low-oxygen biomass-derived pyrolysis oil effluent. 2. The method of claim 1, wherein the first separation conditions include a temperature of from about 60 to about 150 deg. C. 3. The method of claim 1, wherein the second separation conditions include a temperature of from about 10 to about 50 deg. C. 4. The method of claim 1, wherein the step of diluting and heating comprises diluting the biomass-derived pyrolysis oil stream with the phenolic-rich diluent recycle stream at a recycle ratio of from about 3:1 to about 10:1, wherein the recycle ratio is defined by a recycle mass flow rate of the phenolic-rich diluent recycle stream to a pyoil mass flow rate of the biomass-derived pyrolysis oil stream. 5. The method of claim 1, wherein the step of diluting and heating comprises: heating the phenolic-rich diluent recycle stream to form a heated phenolic-rich diluent recycle stream; and   combining the biomass-derived pyrolysis oil stream with the heated phenolic-rich diluent recycle stream to form the heated diluted pyoil feed stream. 6. The method of claim 1, wherein the step of diluting and heating comprises: combining the biomass-derived pyrolysis oil stream with the phenolic-rich diluent recycle stream to form a combined stream; and   heating the combined stream to form the heated diluted pyoil feed stream. 7. The method of claim 1, wherein the hydroprocessing conditions include a reaction temperature of from about 260 to about 375 deg. C. 8. The method of claim 1, wherein the hydroprocessing conditions include a reactor pressure of from about 2 to about 20 MPa gauge. 9. The method of claim 1, wherein the phenolic compounds comprise phenol, alkylphenols, phenol substituted compounds, or combinations thereof. 10. The method of claim 1, wherein the low-oxygen biomass-derived pyrolysis oil effluent has a hydroprocessed organic phase comprising a residual oxygen content of from about 10 to about 20 wt. % of the hydroprocessed organic phase. 11. A method for deoxygenating a biomass-derived pyrolysis oil, the method comprising the steps of: cooling and separating a low-oxygen biomass-derived pyrolysis oil effluent comprising phenolic compounds to form a low-oxygen-pyoil organic phase stream and a phenolic-containing aqueous phase stream;   cooling and separating the phenolic-containing aqueous phase stream to form a phenolic-rich diluent recycle stream and a water-rich stream;   diluting and heating a biomass-derived pyrolysis oil stream with the phenolic-rich diluent recycle stream to form a heated diluted pyoil feed stream; and   contacting the heated diluted pyoil feed stream with a deoxygenating catalyst in the presence of hydrogen in a hydroprocessing reactor at hydroprocessing conditions effective to deoxygenate the heated diluted pyoil feed stream to produce the low-oxygen biomass-derived pyrolysis oil effluent. 12. The method of claim 11, wherein the step of cooling and separating the low-oxygen biomass-derived pyrolysis oil effluent comprises: cooling the low-oxygen biomass-derived pyrolysis oil effluent with a first cooler to form a partially-cooled low-oxygen biomass-derived pyrolysis oil effluent; and   introducing the partially-cooled low-oxygen biomass-derived pyrolysis oil effluent to a first separator to form the low-oxygen-pyoil organic phase stream and the phenolic-containing aqueous phase stream. 13. The method of claim 12, wherein the partially-cooled low-oxygen biomass-derived pyrolysis oil effluent has a temperature of from about 60 to about 150 deg. C. 14. The method of claim 12, further comprising a step of adding at least a portion of the water-rich stream to the low-oxygen biomass-derived pyrolysis oil effluent or the partially-cooled low-oxygen biomass-derived pyrolysis oil effluent prior to the step of contacting. 15. The method of claim 11, wherein the step of cooling and separating the phenolic-containing aqueous phase stream comprises: cooling the phenolic-containing aqueous phase stream with a second cooler to form a partially-cooled phenolic-containing aqueous phase stream; and   introducing the partially-cooled phenolic-containing aqueous phase stream to a second separator to form the phenolic-rich diluent recycle stream and the water-rich stream. 16. The method of claim 15, wherein the partially-cooled phenolic-containing aqueous phase stream has a temperature of from about 10 to about 50 deg. C. 17. The method of claim 11, wherein the step of diluting and heating comprises: heating the phenolic-rich diluent recycle stream to form a heated phenolic-rich diluent recycle stream having a first temperature of from about 285 to about 425 deg. C.; and   combining the biomass-derived pyrolysis oil stream with the heated phenolic-rich diluent recycle stream to form the heated diluted pyoil feed stream having a second temperature of from about 260 to about 375 deg. C. 18. The method of claim 11, wherein the step of diluting and heating comprises: combining the biomass-derived pyrolysis oil stream with the phenolic-rich diluent recycle stream to form a combined stream; and   heating the combined stream to form the heated diluted pyoil feed stream, wherein the heated diluted pyoil feed stream has a temperature of from about 260 to about 375 deg. C. 19. The method of claim 11, wherein the step of cooling and separating the low-oxygen biomass-derived pyrolysis oil effluent further comprises forming a H2-rich gas stream, and wherein the method further comprises a step of: combining at least a portion of the H2-rich gas stream with the phenolic-rich diluent recycle stream prior to the step of diluting and heating.
