Hydrothermal Liquefaction of Jatropha curcas (J. curcas) Under Subcritical Water Conditions: Water and Palm Oil Mill Effluent as Solvents

Engineering Reports, Volume 7, Issue 6, June 2025.
J. curcas was hydrothermally liquefied (HTL) using water and palm oil mill effluent (POME) as a hydrogen donor solvent. Palmitic and oleic acids were detected by the POME analysis utilizing GC–MS by manipulating three parameters (temperature, reaction time, and biomass‐to‐solvent ratio).
