Abstract:
This research focused on conversion of high moisture biomass, namely, empty fruit bunch (EFB), trunk of palm (TOP), and frond of palm (FOP) into bio-oil and other valuable byproducts employing non-catalytic and catalytic hydrothermal liquefaction (HTL). The temperature conditions of the HTL were 250, 275, 300 °C and the residence time were 10, 30, and 60 min. Bio-oil was characterized by Gas Chromatography with Mass Spectrometry. Mass and energy consumption of the process have been calculated. Results showed that the yield of bio-oil from the EFB, TOP, and FOP was around 11-23% and the main component was the phenolic compounds followed by ketones. Other substances such as alcohols, aldehydes, and esters were observed. When adding the KOH catalyst, it can be observed that the main component was changed to ketone. Mass balance showed that the amount of the liquid product was the highest due to the high amount of reacting water used in the experiment whereas the yield of bio-oil and bio-char were relatively low. Two-third of energy consumption belonged to the HTL process while one-third of the total energy consumption was used to evaporating the solvent.
