Hydrothermal liquefaction of algae for biofuel production

Summary

MicroalgaeMicroalgaeMicroalgae are versatile biological cell factories with higher photosynthetic efficiency, fasterMicroalgae growth rate and  area-specific yield than terrestrial biomass. Hydrothermal liquefaction (HTL) is a microalgae conversion technique in hot compressed water (300-375ºC and 10-25 MPa) that requires no drying and less organic solvents, compared to conventional solvent extraction methods. The main product is a liquid energy carrier called bio-oil, but also gas, aqueous and solid products.

The main goal of this work is to find the most suitable feedstock strains and the optimal process conditions for microalgae HTL. This projects aim to provide, through a zero-waste approach, an integrated process scheme of an algae biorefinery concept that includes not only the conversion to biofuel, but also the extraction of other co-products. In such a process, sustainable aspects like the recyclability of nutrients, water or CO2 play a key role.
