Behavior of Surfactants in Oil Extraction by Surfactant-Assisted Acidic Hydrothermal Process from Chlorella vulgaris.

The feasibility of surfactants for enhancement of extraction efficiencies in wet oil extraction through an acidic hydrothermal process was evaluated. Three different types of surfactants were tested: anionic (SDBS and SDS), cationic (CTAB and MBC), and non-ionic (IGEPAL CA-210 and Tween 60). The total fatty acid content of Chlorella vulgaris was 291.
