Evaluation of Potential of Oil Palm Woods for Bioethanol Production
Oil palm trunks (OPTs) are a potential source of sugars for bioethanol production. We determined the glucose, fructose, and sucrose contents of hot water extracts from oil palm trunks (OPTs). Samples of OPTs were obtained from different regions of the trunk, from trunks of different ages (31-, 19-, and 15-year-old) and from fruiting and non-fruiting palms. The extractable sugar contents of whole, upper, and lower regions of each OPT were calculated. Our results indicate that the upper parts of OPTs should be used for bioethanol production, because they yield higher concentrations of sugars than lower parts. In addition, OPTs should be harvested as soon as production of palm oil has been completed and when new male flowers appear to produce a highly concentrated glucose solution for bioethanol production. If these suggestions are followed, the estimated ethanol concentration after fermentation is 3.2％, and estimated ethanol production per harvested area is 3.5 kL/ha.
