This article reports a study of characterization of bio-oil produced from fast pyrolysis of groundnuts shell in a fluidized-bed reactor. The temperature of pyrolysis was varied in the ranges 400-500°C and using a biomass particle size of 250-425 µm. Results showed that the optimum pyrolysis temperatures for groundnuts shell was 475°C, which gave maximum bio-oil yields of 63.48 wt.% on dry biomass basis. The bio-oil products were also tested for their basic properties. Results showed that the water solids and ash contents of the bio-oil were 18.56 wt.%, 0.89 wt.% and 0.03 wt.%, respectively. Moreover, the density, pH value, low heating value (LHV) and viscosity measured to be 1,215 kg/m3, 4.20, 31.07 MJ/kg and 24.56 cSt, respectively.
