Fig. 6. Carbon balance from the continuous hydrothermal liquefaction of nutrient-depleted Oedogonium: (a) at various experiment conditions (temperature, algae concentration and
residence time) in water, and (b) with different co–solvents at 350 °C, 3 min and 5 wt.% loading. *Loss is determined by difference. Average of duplicates (n ≥ 4) are reported.
Maximum relative errors for biocrude, aqueous, solid and gas carbon recovery are 5%, 4%, 9% and 5%, respectively. Error bars are presented in the figure.
