METHOD FOR PRODUCING FUEL OIL BASE

Document Type and Number:

WIPO Patent Application WO/2013/115137

Kind Code:

A1

Abstract:

A method for producing a fuel oil base, provided with: a first step for aerobically culturing microalgae Euglena under nitrogen-deficient conditions; a second step for adding a nutrient source to a solution to be treated, the solution containing the microalgae Euglena cultured in the first step, and then setting the dissolved oxygen concentration of the solution to be treated at 0.03 mg/L or lower, conducting anaerobic fermentation of the microalgae Euglena, and obtaining a wax ester; and a third step for hydrogenating stock oil containing the wax ester and obtaining a fuel oil base.
