A process useful for treating biologically derived oils in the production of biofuels is described. A biologically derived oil feed is deoxygenated by contacting the feed with a metal titanate catalyst comprising a metal titanate having an MTiO3 perovskite structure wherein M is a metal having a valence of 2+. The process does not require the addition of hydrogen.

1. A process for removing oxygen from a biologically derived oil, consisting of: contacting a feed comprising a biologically derived oil containing 0-30 wt. % fatty acids having an initial oxygen content with a catalyst consisting essentially of a metal titanate having an MTiO3 wherein M is a metal
1. A process for removing oxygen from a biologically derived oil, consisting of: contacting a feed comprising a biologically derived oil containing 0-30 wt. % fatty acids having an initial oxygen content with a catalyst consisting essentially of a metal titanate having an MTiO3 wherein M is a metal having a valence of 2+,thereby resulting in a product having a final oxygen content less than the initial oxygen content of the feed;wherein the feed is contacted with the catalyst without the addition of hydrogen gas for the removal of oxygen. 2. The process of claim 1, wherein the product has a final oxygen content at least 20% less than the initial oxygen content of the feed. 3. The process of claim 1, wherein the product has a final oxygen content at least 50% less than the initial oxygen content of the feed. 4. The process of claim 1, wherein the biologically derived oil is derived from a plant source, an animal source, or mixtures thereof. 5. The process of claim 1, wherein the biologically derived oil comprises FAME. 6. The process of claim 1, wherein the biologically derived oil comprises pyrolysis oil. 7. The process of claim 1, wherein the catalyst comprises at least 1% by weight metal titanate. 8. The process of claim 1, wherein the catalyst comprises at least 5% by weight metal titanate. 9. The process of claim 1, wherein the catalyst comprises at least 10% by weight metal titanate. 10. The process of claim 1, wherein the catalyst comprises at least 80% by weight metal titanate. 11. The process of claim 1, wherein the catalyst further comprises a support selected from the group consisting of silica, alumina, silica-alumina, carbon, molecular sieves and mixtures thereof. 12. The process of claim 1, wherein the feed is contacted with the catalyst at a temperature of less than 500° C. 13. The process of claim 1, wherein the feed is contacted with the catalyst at a temperature of less than 400° C. 14. The process of claim 1, wherein the feed is contacted with the catalyst at a temperature of between 250° C. and 350° C. 15. The process of claim 1, wherein the feed is contacted with the catalyst at a pressure of between 100 kPa and 1000 kPa absolute. 16. The process of claim 1, wherein the catalyst comprises a metal titanate selected from the group consisting of magnesium titanate, copper titanate, nickel titanate, iron(II) titanium oxide, cobalt titanium oxide, manganese(II) titanium oxide, lead(II) titanate, calcium titanate, barium titanate and zinc titanate. 17. The process of claim 1, wherein the catalyst comprises a metal titanate selected from the group consisting of calcium titanate, barium titanate and zinc titanate. 18. The process of claim 1, wherein the feed is contacted with the catalyst at a LHSV of between 0.2 and 5 h−1. 19. The process of claim 1, wherein the feed is contacted with the catalyst in a fixed bed reactor. 20. The process of claim 1, wherein the feed is contacted with the catalyst in a slurry bed reactor. 21. The process of claim 1, wherein the metal titanate has a perovskite structure. 22. The process of claim 1, wherein the product having a final oxygen content less than the initial oxygen content of the feed is a transportation fuel. 23. The process of claim 1, wherein the product having a final oxygen content less than the initial oxygen content of the feed is a biodiesel.
