| Outline of Final Research Achievements |
To reduce total biodiesel fuel (BDF) production to less than 200 yen/L-BDF, the reduction of raceway pond construction cost from 25 to 5 Myen/ha, recycling 90% of nutrients by hydrothermal liquefaction (HTL) are required. The power of paddle wheel and dewatering have to be reduced 1/10 compared with the present technology. We calculated energy consumption and cost by introducing energy-saving technology in solvent extraction process. We found 0.5wt% of activated carbon significantly enhances total nitrogen recovery in the aqueous phase in hydrothermal liquefaction. Phosphorus can be removed from waste water by using anaerobic and aerobic activated sludge for relatively long time. FAME yields from HTL oil were significantly higher than those from solvent-extracted oil under all investigated reaction conditions. Thus, we investigated the reactivity of solid residue from HTL of microalgae in oxidizing atmosphere by using a thermobalance reactor.
