Abstract:

The objective of this study was to examine the effect of pyrolysis temperature on bio­oil’s physical properties. Bio­oil was produced in a bench scale auger reactor from locally available biomass feedstocks. Agricultural wastes (poultry litter and peanut hulls), pine wood (abundant in the southern United States), and an energy crop (switchgrass) were selected as feedstocks for bio­oil production. Experiments were performed at temperatures from 450 oC to 600 oC, in increments of 50 oC. The bio­oil yield varied from 18 wt.% to 36.6 wt.% (wet basis) and the switchgrass gave the highest yield among the feedstocks tested in this study. The highest bio­oil yield for pine wood (36 wt.%) was obtained at 600 °C whereas the highest yields for switchgrass (36.6 wt%), peanut hulls (34.2 wt.%) and poultry litter (22.9 wt.%) were obtained at 450 °C. Physical properties, such as density, pH, water content and viscosity were analyzed in this study. The feedstock and pyrolysis temperature influenced the physical properties of bio­oil. The bio­oil derived from poultry litter was almost neutral or basic whereas the other three feedstocks gave highly acidic bio­oil.
