Abstract: A supercritical ethylene extraction process for selectively recovering a phenolic compound from bio-crude and/or bio-oil comprises providing a reactor containing bio-crude and/or bio-oil, wherein the reactor has an operating pressure, introducing an ethylene solvent at the operating pressure to the reactor, and using the ethylene solvent at the operating pressure to extract the extracted portion from the feedstock, wherein the extracted portion comprises the selected phenolic compound at a concentration equal to or greater than 70 wt % on a dry basis.
