Abstract
A process is provided for upgrading low value lipid feedstocks for refinery processing. The process includes (a) treating a lipid feedstock comprising at least one fatty acid with a metal oxide catalyst on an oxide support under treating conditions to produce a treated stream, wherein the treating conditions include a temperature in a range of from 400° C. to 700° C.; a pressure in a range of from 0 to 10 MPa; and a liquid hourly space velocity in a range of from 0.1 to 10 h; and (b) fractionating the treated stream to obtain a gaseous fraction and a liquid fraction comprising a bio-oil; wherein the bio-oil has a lower content of oxygen and impurities as compared to the lipid feedstock.
