Abstract: Crude algae oils are thermally-treated at temperature(s) in the range of 300-600° C., without catalyst and/or the addition of hydrogen, to produce a higher grade, cleaner algae oil with, for example, reduced oxygen, boiling range, viscosity and/or density, and acid number, in addition, because the thermal treatment reduces metals in the oil and produces carbonaceous solids, it is expected that catalyst deactivation by algae oil feedstocks will be greatly reduced if the crude algae oil or fractions thereof are thermally-treated prior to catalytic upgrading. Oxygen, fatty acids, metals, and metalloids are reduced/removed by the thermal treatment, so that RBI) processing of the crude bio-oil may be reduced or eliminated, and requirements for further deoxygenation and hydrotreating of the thermal products are reduced or eliminated.
