Microalgal biocrude was produced by hydrothermal liquefaction (HTL) of native microalgae slurry using a bench-scale continuous flow tubular reactor. The native algae was harvested in an open raceway pond in Minamisoma city, Fukushima prefecture. The slurry of native algae was continuously injected to a tubular reactor by high-pressure pumps, and the temperature was increased gradually through preheating tubes. The slurry eventually reached the reaction tube, which was held at 350 °C and 19.5 MPa, where it was kept for 6 min. The yield of biocrude recovered in a tank No. 1 was 43.0 wt%. The higher heating value (HHV) of biocrude was 29.1 MJ/kg-dry (34.5 MJ/kg-daf) calculated by the chemical elements using Dulong's formula.
