Bio-oil from Fast Pyrolysis of Empty Fruit Bunch at Various Temperature

World concern about depletion of fossil fuel and energy security supply has driven into increasing awareness about biomass derived energy. Empty fruit bunch (EFB), one of the major palm oil-derived biomass available in Indonesia, is a potential source for fuel production. Pyrolitic conversion of EFB to bio-fuels is being considered for national energy security and environmental advantages. The objective of the work is to determine the effect of reaction temperature and time on the EFB fast pyrolysis optimization. Elemental analysis composition and physical properties of bio-oil show increase in carbon content, decrease in oxygen, hydrogen, and nitrogen content with increases the pyrolysis temperature.
