摘要: 利用层析法对玉米芯快速热解油进行分析。结果表明,裂解温度对热解油产率及其族馏分构成的影响很大。通过气相色谱(GC)分析表明,脂肪族馏分碳数分布主要在C12~34,在烷烃碳数分布上,脂肪族馏分与柴油相当。并利用傅里叶红外光谱(FT-IR)、核磁共振氢谱(1H-NMR)分析了600℃下得到的热解油特征,表明玉米芯快速热解油作为燃料和高品位化学品原料来源具有潜在的发展前景。Abstract: 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 C12~34. 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.
