权利要求: - 32 -CLAIMSWe claim:1. A biofuel, comprising: a mixture having a gasoil generated from hydropyrolysis and hydroconversion of a solid biomass containing lignocellulose and an isomerized hydroprocessed ester and fatty acid (HEFA) generated from hydrotreating a renewable resource comprising fats and oils, wherein the gasoil has a cetane index less than 46 and at least 10 parts per million weight (ppmw) of a heteroatom, and wherein a cetane index of the biofuel is greater than 46.2. The biofuel of claim 1, wherein the gasoil is present in an amount less than the HEFA.3. The biofuel of claim 1, wherein the gasoil is present in an amount of from between approximately 5 volume % (vol%) and 60 vol%.4. The biofuel of claim 3, comprising a lubricity of less than approximately 450 micrometers (pm).5. The biofuel of claim 4, comprising an oxidation stability of less than 25 grams/cubic meter (g/m3).6. The biofuel of claim 1, wherein the gasoil has an initial boiling point greater than 145 °C.7. The biofuel of claim 1, wherein the at least one heteroatom is nitrogen, sulfur, or both.8. The biofuel of claim 1, wherein the gasoil is generated by a hydroprocess comprising: hydropyrolysing the solid feedstock in the first stage hydropyrolysis reactor to generate a product stream comprising partially deoxygenated hydropyrolysis product, H2O, H2, CO2, CO, Ci - C3 gases, char and catalyst fines; feeding at least a portion of the product stream to a second stage hydroconversion reactor comprising one or more hydroconversion catalysts; and hydroconverting the partially deoxygenated hydropyrolysis product in the product stream to generate a vapor phase product comprising substantially fully deoxygenated hydrocarbon product, H2O, CO, CO2, and Ci - C3 gases;- 33 - condensing the vapor phase product to generate a deoxygenated hydrocarbon liquid comprising the substantially fully deoxygenated hydrocarbon product having one or more heteroatoms, wherein the substantially fully deoxygenated hydrocarbon product comprises the gasoil.9. A process for producing a biofuel comprising: feeding a solid feedstock and hydrogen to a first stage hydropyrolysis reactor, wherein the first stage hydropyrolysis reactor comprises one or more deoxygenation catalysts, and wherein the solid feedstock comprises biomass containing lignocellulose; hydropyrolysing the solid feedstock in the first stage hydropyrolysis reactor to generate a product stream comprising partially deoxygenated hydropyrolysis product, H2O, H2, CO2, CO, Ci - C3 gases, char and catalyst fines; feeding at least a portion of the product stream to a second stage hydroconversion reactor comprising one or more hydroconversion catalysts; hydroconverting the partially deoxygenated hydropyrolysis product in the product stream to generate a vapor phase product comprising substantially fully deoxygenated hydrocarbon product, H2O, CO, CO2, and Ci - C3 gases; condensing the vapor phase product to generate a deoxygenated hydrocarbon liquid comprising the substantially fully deoxygenated hydrocarbon product, wherein the substantially fully deoxygenated hydrocarbon product comprises a gasoil having a cetane index of less than 46 and at least 10 parts per million weight (ppmw) of a heteroatom; and mixing the gasoil with an isomerized hydroprocessed ester fatty acid (HEFA) to generate the biofuel, wherein a cetane index of the biofuel is greater than 46.10. The process of claim 9, wherein the isomerized HEFA is produced by hydroprocessing a renewable resource comprising fats and oils.11. The process of claim 9, wherein the gasoil is present in an amount less than the HEFA.12. The process of claim 9, wherein mixing the gasoil with the isomerized HEFA comprises adding between approximately 10 volume (vol) % and 35 vol % of the isomerized HEFA to the gasoil.13. The process of claim 9, wherein a lubricity of less than approximately 450 micrometers (pm) and an oxidation stability of less than approximately 25 grams/cubic meter (g/m3).14. The process of claim 9, wherein the heteroatom is nitrogen, sulfur, or both.
