Hydrothermal liquefaction of lipid-extracted Tetraselmis sp. feedstock containing 80 wt.% water was conducted in a batch reactor at different temperatures (300, 325, and 350oC) and reaction times (5, 10, 20, 40, and 60 min). The biofuel yield, elemental composition and higher heating value obtained at various reaction conditions were used to predict the optimum conditions for maximizing energy recovery of biofuel with good quality. A maximum energy recovery of 67.6% was obtained at 325°C and 40 min with a high energy density of 31.8 MJ/kg and lower contents of nitrogen and oxygen. Results showed that reaction conditions of 325°C, 40 min was most suitable for maximizing energy recovery while at the same time achieving improved quality of biofuel. |
