Disclosed herein are methods and systems for upgrading (for example, removing heteroatoms, metals, or metalloids) an oil composition derived or extracted from a biomass. The upgraded oil composition can be used to make a desired product, for example, a fuel product.
대표청구항▼
1. A method of producing diesel fuel or diesel blendstock from an algal-oil feedstock, comprising: a) providing an algal-oil feedstock comprising greater than about 0.0528% to about 4.8% w/w nitrogen, greater than about 6.81% to about 15.64% w/w oxygen, greater than about 0.0344% to about 0.9% w/w s
1. A method of producing diesel fuel or diesel blendstock from an algal-oil feedstock, comprising: a) providing an algal-oil feedstock comprising greater than about 0.0528% to about 4.8% w/w nitrogen, greater than about 6.81% to about 15.64% w/w oxygen, greater than about 0.0344% to about 0.9% w/w sulfur, greater than about 0.0006% to about 0.83% w/w phosphorus, and greater than about 0.6% to about 62% w/w chlorophyll or chlorophyllide; andb) refining the algal-oil feedstock to obtain the diesel fuel or diesel blendstock by a method comprising, hydrotreating the algal-oil feedstock at a temperature of from about 315 to about 480° C. (from about 600 to about 900° F.), a total pressure and/or hydrogen partial pressure of from about 100 to about 3000 psi, a hydrogen to oil ratio of from about 100 to about 2000 scf/Bbl, and a space velocity from about 1.5 vol of oil per vol of catalyst per hour to about 8 vol of oil per vol of catalyst per hour;wherein the diesel fuel or diesel blendstock comprises an oxygen level of less than or equal to about 0.5% w/w, a nitrogen level of less than or equal to about 0.5% w/w, and less than or equal to about 1 ppm phosphorus. 2. The method of claim 1, wherein the refining removes from the algal-oil feedstock at least one of the following: Boron (B), Calcium (Ca), Chromium Cr), Copper (Cu), Iron (Fe), Lead (Pb), Lithium (Li), Magnesium (Mg), Manganese (Mn), Nickel (Ni), Phosphorus (P), Potassium (K), Silicon (Si), Sodium (Na), Strontium (Sr), or Zinc (Zn). 3. The method of claim 1, wherein hydrotreating comprises the use of at least one catalyst comprising: a metal such as Ni/Mo, Co/Mo, Co/W, W/Mo, or Ni/W; a noble metal; a zeolite; Ni/Mo supported on alumina; Co/Mo supported on alumina; Ni/W supported on alumina; a metal of Group VIA, Group VIb, or Group VIII of Periodic Table of Elements; or a metal of Group VIb or Group VIII of Periodic Table of Elements supported on a porous refractory oxide carrier. 4. The method of claim 1, wherein refining of the algal-oil feedstock further comprises refining, bleaching, and deodorizing the algal-oil feedstock prior to hydrotreating. 5. The method of claim 1, wherein the algal-oil feedstock is derived from Chlamydomonas reinhardtii, Dunaliella salina, Haematococcus pluvialis, Scenedesmus dimorphus, Dunaliella viridis, Dunaliella tertiolecta, Nannochloropsis oculata, Nannochloropsis oceania, a Chlorella species, or Nannochloropsis salina. 6. A method of producing jet fuel from an algal-oil feedstock, comprising: a) providing an algal-oil feedstock comprising greater than about 0.0528% to about 4.8% w/w nitrogen, greater than about 6.81% to about 15.64% w/w oxygen, greater than about 0.0344% to about 0.9% w/w sulfur, greater than about 0.0006% to about 0.83% w/w phosphorus, and greater than about 0.6% to about 62% w/w chlorophyll or chlorophyllide; andb) refining the algal-oil feedstock to obtain the jet fuel by a method comprising, hydrotreating the algal-oil feedstock at a temperature of from about 315 to about 480° C. (from about 600 to about 900° F.), a total pressure and/or hydrogen partial pressure of from about 100 to about 3000 psi, a hydrogen to oil ratio of from about 100 to about 2000 scf/Bbl, and a space velocity from about 1.5 vol of oil per vol of catalyst per hour to about 8 vol of oil per vol of catalyst per hour;wherein the jet fuel comprises a freezing point of less than −47° C., a smoke point of greater than about 30° C., and about 1.6 ppm sulfur. 7. The method of claim 6, wherein the refining removes from the algal-oil feedstock at least one of the following: Boron (B), Calcium (Ca), Chromium Cr), Copper (Cu), Iron (Fe), Lead (Pb), Lithium (Li), Magnesium (Mg), Manganese (Mn), Nickel (Ni), Phosphorus (P), Potassium (K), Silicon (Si), Sodium (Na), Strontium (Sr), or Zinc (Zn). 8. The method of claim 6, wherein hydrotreating comprises the use of at least one catalyst comprising: a metal such as Ni/Mo, Co/Mo, Co/W, W/Mo, or Ni/W; a noble metal; a zeolite; Ni/Mo supported on alumina: Co/Mo supported on alumina; Ni/W supported on alumina; a metal of Group VIA, Group VIb, or Group VIII of Periodic Table of Elements; or a metal of Group VIb or Group VIII of Periodic Table of Elements supported on a porous refractory oxide carrier. 9. The method of claim 6, wherein the refining of the algal-oil feedstock further comprises cracking, isomerization and fractionation. 10. The method of claim 6, wherein the algal-oil feedstock is derived from Chlamydomonas reinhardtii, Dunaliella salina, Haematococcus pluvialis, Scenedesmus dimorphus, Dunaliella viridis, Dunaliella tertiolecta, Nannochloropsis oculata, Nannochloropsis oceania, a Chlorella species, or Nannochloropsis salina. 11. The method of claim 1, wherein said hydrotreating is a single stage hydrotreating at a pressure from about 1000 to about 3000 psi to remove said chlorophyll or chlorophyllide form said algal-oil feedstock. 12. The method of claim 6, wherein said hydrotreating is a single stage hydrotreating at a pressure from about 1000 to about 3000 psi to remove said chlorophyll or chlorophyllide form said algal-oil feedstock.
