Botryococcus braunii produces a lot of hydrocarbons, and accumulates them outside the cell. Generally, the drying process is necessary for the hydrocarbon recovery, and the process consumes a lot of energy. From the results of experiments, it became clear that hydrocarbon can be extracted by removing the liquid phase of the thermally treated concentrated slurry. This method can omit the drying process consuming a lot of energy. Next, four reaction conditions were changed; that are heating temperature, moisture content at extraction, extraction time, and solvent ratio. These reaction conditions affect process energy and cost. The amount of hydrocarbons recovered under each condition was quantified. If moisture content at extraction is 82.5% to 87.5%, not less than 95% of hydrocarbon is recoverable in the small amount of hexane by multiple extractions.
