Hydrothermal liquefaction of microalgae: Influence of varying cell compositions on biocrude yield and quality
… on HTL biocrude yield and chemical composition. Nannochloropsis oculata was cultivated under depleting nitrogen levels to obtain biomass with variable cell compositions (17–59 %dw lipids; 45–17 %dw proteins; 11–22 %dw carbohydrates). HTL of harvested biomass was conducted at commonly used process …
