Production of Fuel-Like Fractions by Fractional Distillation of Bio-Oil from Açaí (Euterpe oleracea Mart.) Seeds Pyrolysis

This work investigates the effect of production scales (laboratory, bench, and pilot) by pyrolysis Açaí (Euterpe oleracea Mart.) seeds at 450 °C 1.0 atmosphere, on yields reaction products acid value bio-oils. The experiments were carried out in batch mode using a laboratory scale reactor 143 mL, bench 1.5 L, pilot L (≈1:10:1000). bio-oil was obtained scale, fractionated distillation to produce biofuel-like fractions. column. physical-chemistry properties (density, kinematic viscosity, value, refractive index) bio-oils fractions determined. qualitative analysis determined FT-IR chemical composition GC-MS. showed from 4.37 13.09 (wt.%), decreasing with volume. varied 68.31 70.26 mg KOH/g. produced gasoline, light kerosene, kerosene-like fuel fractions, 16.16, 19.56, 41.89 respectively. increase temperature. identified presence functional groups characteristic hydrocarbons (alkenes, alkanes, aromatics, aromatics rings) oxygenates (carboxylic acids, ketones, esters, ethers, alcohols, phenols). GC-MS 48.24 (area.%) 51.76 21.52 78.48 scale. gasoline-like fraction composed 64.0 36.0 oxygenates, 66.67 33.33 19.87 81.13 oxygenates.
