Effects of the use of acetone as co-solvent on the financial viability of bio-crude production by hydrothermal liquefaction of CO2 captured by microalgae

Journal of CO2 Utilization
Hydrothermal Liquefaction (HTL) is a promising technology to produce biocrude from microalgal biomass that has captured gaseous CO2. However, several problems of this technology must still be solved to make it economically and technically feasible.
