Outline of Final Research Achievements

Microalgae is gaining attention as a potential new feedstock for biorefineries. Current methods used to obtain oil from microalgae require drying steps, which consumes much energy and the usage of organic solvents. In this work, we developed a wet extraction method using surfactant active ionic liquids (IL) and supercritical CO2 (scCO2). IL are applied to solubilize microalgae oil in water, and to improve contact efficiency with scCO2. Wet oil extraction was conducted from microalgae (Botryococcus braunii) in the cultivation solution with IL and scCO2 which confirmed that the extraction yield increased greatly by adding ILs in the culture compared to pure scCO2 extraction.
