1. A process for generating a renewable stream, the process comprising:
(a) extracting oxygenated molecules from a bio-oil derived from a lignocellulosic biomass using a fatty acid stream as a solvent at a temperature in a range of 30 to 100° C., a residence time from 0 to 10 h and a fatty acid stream: bio-oil ratio between 0.1 and 5 (w/w);
(b) separating an extract phase and a raffinate phase, where the extract phase contains fatty compounds and the oxygenated molecules extracted from the bio-oil; and
(c) hydrogenating the extract phase under conditions effective to hydroprocess esters and fatty acids to produce a renewable fuel product.
