Conversion of oil palm trunk into bio-oil via treatment with subcritical water


Siajam, Shamsul Izhar and Muda, Noor Azura and Yoshida, Hiroyuki and Ishak, Hazwani and Ismail, Mohd Halim Shah (2019) Conversion of oil palm trunk into bio-oil via treatment with subcritical water. Journal of Wood Chemistry and Technology, 39 (4). pp. 255-269. ISSN 1532-2319


Subcritical water was applied to produce bio-oil from a 21-year-old abandoned oil palm trunk (OPT). The effects of reaction temperature, time, part of trunk taken, and optimum reaction condition were investigated. Higher heating values (HHVs), CHNS/O elemental and GC-MS analysis were performed to characterize the bio-oil. The subcritical water temperatures were manipulated between 100 °C and 370 °C with 10 °C intervals and the reaction time was varied between 6 s and 20 min. The maximum yield of bio-oil from subcritical water treatment of top and bottom part of OPT was 0.27 and 0.30 kg/kg-dry OPT, respectively. The optimum reaction time and temperature was 5 min and 330 °C. The highest HHV of the bio-oils derived from the top and bottom part of OPT was 33.2 MJ/kg and 26.4 MJ/kg, respectively. From GC-MS measurement, the bio-oil contained phenolic compounds. The bio-oil derived from OPT obtained from subcritical water treatment had high HHV and comparable to other liquid fuels.
