A process for producing a hydrocarbon from biomass. A feed stream containing biomass having fatty acids, mono-, di-, and/or triglycerides, and a phosphorus content of between about 1 wppm and about 1,000 wppm is provided. A heated hydrocarbon solvent and a hydrogen-rich gas are provided. The feed stream, the heated hydrocarbon solvent, and the hydrogen-rich gas are combined in the presence of a low activity hydrogenation catalyst. A spent low activity hydrogenation catalyst is recovered at the end of a run wherein the spent low activity hydrogenation catalyst contains at least 3% by weight phosphorus.

The method of claim 1 wherein the low activity hydrogenation catalyst is a sulfided mono-metallic base metal catalyst. 4. The method of claim 3 wherein the low activity hydrogenation catalyst contains between about 2% and about 10% by weight molybdenum or tungsten. 5. The method of claim 1 wherein the spent low activity hydrogenation catalyst contains between about 6% and about 10% phosphorus by weight. 6. The method of claim 1 wherein the spent low activity hydrogenation catalyst contains between about 9% and about 10% phosphorus by weight. 7. The method of claim 1 wherein the product of the step of combining the feed stream, the heated hydrocarbon solvent, and the hydrogen-rich gas in the presence of a low activity hydrogenation catalyst is further reacted in the presence of a high activity hydrogenation catalyst. 8. The method of claim 7 wherein the high activity hydrogenation catalyst is a bimetallic base metal catalyst. 9. The method of claim 8 wherein the high activity hydrogenation catalyst contains at least 16% total metals from the group comprising nickel, cobalt, molybdenum, and tungsten. 10. The method of claim 1 wherein phosphorus is recovered from the spent low activity hydrogenation catalyst. 11.
