Abstract:
The influence of temperature on the yield and properties of pyroligneous oil produced from biomass from Apa wood (Afzelia africana), Iroko wood (Melicia excelsa) and palm kernel (Elais guineensis) shells were investigated at 400, 500, 600, 700 and 800 °C in an in-house fabricated fixed-bed reactor. The syngas and pyroligneous oil namely: pyrolysis oil and tar were studied. The biomass species and pyrolysis temperature significantly influenced the oil yield (p<0.05). The chemical compositions of the pyrolysis oil were characterized using Fourier transform infrared (FTIR) and the spectra showed the presence of ketonic (acid) and olefinic compounds. The ketonic acid is responsible for the high acidic nature of the oil. Density of the pyrolysis oil obtained from Apa, Iroko and PKS were not temperature and biomass source dependent.
Keywords: biomass, pyrolysis, fixed bed reactor
