Characteristics of pyrolytic oil produced from fast pyrolysis of corncob

 The characteristics of pyrolytic oil from fast pyrolysis of corncob in a built-in fast pyrolysis fixed-bed reactor were studied through column chromatographic separation. It is shown that the pyrolysis temperature has a great effect on the yield and the compositions of the bio-oil. The GC chromatogram of the aliphatic fraction show that the carbon distributions are between C_12~34. Carbon distributions of the aliphatic fraction are similar to those in diesel fuel. The bio-oil obtained at 600℃ was analyzed using FT-IR and ¹H-NMR. The chemical characterization shows that the bio-oil from corncob may be potentially valuable as a fuel and chemical feedstock.
