Abstract Download PDFHydrothermal liquefaction (HTL) was applied to investigate the feasibility in
converting cassava rhizome (CR) to biocrude oil (BO) as an alternative biofuel.
HTL was performed at various process temperatures (250 – 300°C) and retention
times (15 – 60 min). Process temperature is a vital key parameter on fuel
properties of BO. Yield and HHV of BO were in the range of 22.90 – 31.00%, and
19.80 – 23.08 MJ/kg, respectively. The BO with maximum energy recovery
efficiency (ERE) was derived at 275°C for 30 min. BO contains ketones and
aldehydes, phenols, hydrocarbons, and alcohols which are in good agreement
with chemical functional groups of FTIR spectra. The chemical reactions during
BO formation were also proposed in this study.
