  6. Then, analytical work was carried out as follows : the ultimate analysis and physi - chemical analysis of the pyrolytic oil comprised a sketch of the fuel properties of the oil ; then, through the distillation analysis of the oil, the fraction composition of the " unrefined " oil was known. after that, a general knowledge of the aromaticity and saturation of the hydrocarbons in the oil was provided by the outcome of the ft - ir functional group analysis. also, from the analysis, the form of the polar functional groups and their distribution in different fractions of the oil were learned

    文中首先對不同熱解溫度下熱解油產率進行分析討論，然後，針對熱解油品質進行了一系列分析：通過元素組成和理化特性的分析，對熱解油作為燃料特性有了一個大致了解；通過實沸點蒸餾分析，得到熱解油作為一種未提煉油的餾分分佈，並為后續熱解油餾分的細入分析提供了前提；通過對熱解全油和各窄餾分的ft - ir官能團分析，對熱解油的芳香性、不飽和性有了整體的了解，並且清楚了熱解油中的極性官能團存在型式及其在熱解油不同餾分中的分佈。
  7. Close cut separation
