TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The method (m1) further comprise extracting a bio-oil from a biomass feed comprising algae by exposing the biomass feed to water under effective hydrothermal processing conditions including a temperature of at least 200 degrees C, preferably at least 250 degrees C or at least 300 degrees C, where the feedstock comprises the extracted bio-oil, and the feedstock optionally has a nitrogen content of at least 1.5 wt.% e.g. at least 2 wt.%. In the method (m1): the weight percentage of ketones in the effluent is at least 50% of the combined weight percentage of fatty amides, fatty acids and fatty acid derivatives in the feedstock; the fatty acid derivatives comprise glycerides and/or the fatty amides comprise substituted fatty amides; and the feedstock is exposed to the first catalyst under effective conditions to form an effluent that further comprises nitriles, where the first catalyst comprises at least one of magnesium oxide, calcium oxide (both preferred) and/or aluminum oxide. In the method (m2), the feedstock is exposed to the first catalyst in the presence of hydrogen. The methods further comprise fractionating the deoxygenated effluent to form at least a diesel boiling range fraction and a lubricant boiling range fraction. Preferred Components: The hydroprocessing catalyst comprises zeolite socony mobil (ZSM)-48 and/or ZSM-23, with a hydrothermally stable binder comprising titanium oxide (preferred), zirconium oxide and/or cerium oxide. The first catalyst comprises a clay containing at least one of a rare earth metal salt, an alkali metal salt and an alkaline earth metal salt. The rare earth metal salt, alkali metal salt and/or alkaline earth metal salt comprise a salt of magnesium, calcium (both preferred), sodium, potassium, rubidium, cesium, strontium, barium, lanthanum, cerium and/or yttrium. The first catalyst further comprises a hydrothermally stable support comprising titanium oxide, zirconium oxide and/or cerium oxide. The hydrothermally stable support comprises titanium oxide or zirconium oxide. EXAMPLE - No suitable example given.
