The aim of this work is the characterization of biogenic residues and their possible use as feedstock for hydrothermal liquefaction. In the course of this work ten different biogenic residues and two different microalgae strains were tested for their applicability in hydrothermal liquefaction. Experiments were carried out at 350 °C with a holding time of 15 minutes. The product yields could be determined via a mass balance. Biocrude yields between 9.43 % (green waste) and 70.40 % (grease separator) were achieved. The oxygen content was reduced in all biocrude samples during HTL in favour of higher carbon contents compared to the raw material samples.
