1. A process for converting a lipid feedstock to a treated stream, the process comprising:
providing the lipid feedstock to a reactor such that the lipid feedstock reacts with at least one bed of catalyst particles producing the treated stream, wherein the catalyst particles have a diameter of 0.01 to 0.5 mm and comprise calcium oxide on an alumina support; and
fractionating the treated stream to obtain a gaseous fraction and a liquid fraction, the liquid fraction comprising a bio-oil having a lower content of oxygen and impurities than the lipid feedstock.
