Abstract: A process for selectively recovering a phenolic compound from feedstock comprising bio-crude and/or bio-oil is described. The recovery efficiency of the selected phenolic compound is greater than 70 wt % and the purity of the recovered selected phenolic compound is higher than 80 wt %. The process comprises distilling the feedstock to isolate the selected phenolic compound in a first distillate fraction comprising the selected phenolic compound, concentrating the selected phenolic compound from the first distillate fraction in a concentrated mixture, and purifying the concentrated mixture to recover the selected phenolic compound.

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.
