The invention is an integrated thermochemical process, also known as a looped-oxide catalysis, for providing an upgraded biofuel composition from a biomass-derived feedstock. First, the feedstock is deoxygenated through reaction with a low-valence metal oxide or zero-valent metal to yield a deoxygenated biofuel composition and a high-valence metal oxide. Second, the low-valence metal oxide is regenerated by reducing the high-valence metal oxide using solar thermal energy.

1. An integrated thermochemical process for providing an upgraded biofuel composition from a biomass-derived feedstock, comprising: deoxygenating the feedstock through reaction with a low-valence metal oxide or zero-valent metal to yield a deoxygenated biofuel composition and a high-valence metal oxide; andreducing the high-valence metal oxide using solar thermal energy, thereby regenerating the low-valence metal oxide. 2. The process of claim 1, wherein the deoxygenating is conducted at a pressure of 1-50 bar. 3. The process of claim 1, wherein: deoxygenating the feedstock is accomplished through a hydrodeoxygenation process; andthe hydrodeoxygenation process is conducted using H2 generated through an in situ reaction of the low-valence or zero-valent metal oxide with water inside a reactor. 4. The process of claim 1, wherein the feedstock is a bioliquid. 5. The process of claim 1, wherein the feedstock is bio-oil derived from thermal processing of lignocellulosic biomass. 6. The process of claim 1, wherein said zero-valent metal, said low-valence metal oxide, or said high-valence metal oxide comprises a metal that is selected from the group consisting of: Fe, Zn, Ge, Mo, Cd, Sn, Ce, and W. 7. The process of claim 1, wherein said zero-valent metal, said low-valence metal oxide, or said high-valence metal oxide acts as a catalyst in determining selectivity towards targeted deoxygenation products. 8. The process of claim 1, wherein said zero-valent metal or said low-valence metal oxide acts as a bulk reducing agent and oxygen conductor in removing oxygen heteroatoms from the feedstock. 9. The process of claim 1, wherein reducing the high-valence metal oxide is performed within a solar thermal reactor. 10. The process of claim 1, wherein the deoxygenating of the feedstock occurs at a temperature between 300-700 K. 11. The process of claim 1, wherein the regenerating of the low-valence metal oxide occurs at a dissociation temperature of the high-valence metal oxide. 12. The process of claim 11, wherein the regenerating of said low-valence metal oxide occurs at a temperature between 1000-2000 K. 13. The process of claim 1, wherein the low-valence metal oxide or zero-valent metal is selected from the group consisting of: FeO, Zn, Cd, SnO and Ce2O3. 14. The process of claim 1, wherein the high-valence metal oxide is selected from the group consisting of: Fe3O4, ZnO, CdO, SnO2, and CeO2. 15. The process of claim 1, wherein regenerating a low-valence metal oxide is accomplished in a solar electrothermal reactor where the metal oxide is dissolved in a molten electrolyte. 16. The process of claim 1, wherein the deoxygenating is conducted at a pressure of 1-10 bar. 17. The process of claim 1, wherein the deoxygenating is conducted at ambient total pressure. 18. The process of claim 1, wherein the deoxygenating of the feedstock occurs at a temperature between 400-600 K. 19. The process of claim 11, wherein the regenerating of said low-valence metal oxide occurs at a temperature between 1400-1600 K. 20. The process of claim 11, wherein the regenerating of said low-valence metal oxide occurs at a temperature of 1500 K.
