In this work, the dried seeds of Açaí (Euterpe oleracea Mart) weresubmitted to pyrolysis to produce Bio-Oil. The pyrolysis reaction was carried out in a143 L reactor, operating in batch at 450 ºC and 1.0 atm. Bio-Oil distillation wasperformed on a laboratory-scale column according to the boiling temperature range offossil fuels. The physicochemical characterization of the bio-oil and the distillatefractions (gasoline, kerosene and diesel) were performed by the AOCS, ASTM andABNT/NBR methods in terms of acidity index, density, refractive index and kinematicviscosity. The qualitative analysis of Bio-Oil was performed by FT-IR spectroscopy.Experiments show that the yields of coke and bio-oil gas were 4.39, 35.67 and 30.56 %(by weight), respectively. The density and viscosity of Bio-Oil were 1.0468 g/cm3and68.34 mm²/s, respectively; with acidity index around 70.26 mg KOH/g. Bio-Oildistillation yielded 55.26 % (by weight). Bio-Oil's FT-IR has identified the presence ofhydrocarbons, carboxylic acids, ketones and phenols.
