The temperature effect on the oil yield was discussed at first. 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.
