| 摘 要： | 利用核磁共振波谱仪（NMR）与气相色谱/质谱联用仪（GC/MS）对重质生物油理化性质进行表征，并应用热重分析仪（ TG-DTG）与热裂解仪-气相色谱/质谱联用仪（Py-GC/MS）对重质生物油热解特性进行研究。结果表明：重质生物油主要由芳香族化合物和糖类物质组成。重质生物油在N2氛围下热解主要分为三个阶段: 室温~300℃为蒸发段，300～520℃为热解段，520～800℃为成焦段。重质生物油经不同温度热解后，产物种类有明显差异：中温段（低于500℃）热解时，产物种类随温度的升高逐渐增加；高温段（高于500℃）热解时，随着热解温度的提高，产物种类逐渐趋于稳定。

| Abstract: | The physicochemical properties of heavy bio-oil were characterized by NMR and GC/MS, and thermogravimetric analyzer (TG-DTG) and pyrolysis instrument-gas chromatography/mass spectrometry (Py-GC/MS) was used to study the pyrolysis characteristics of heavy bio-oil. The results indicate that the heavy bio-oil consists of aromatic compounds and saccharides. The first stage is the volatilization of light compounds from ambient temperature to 300℃. The second stage is the pyrolysis, oxidation and polymerization of the heavy compounds at higher temperature (300—520℃). The last stage is the formation of coke (520—800℃). When the pyrolysis temperature is lower than 500℃, the species of products gradually increases with increasing temperature. When the temperature is higher than 500℃, the species of products tends to be stable with increasing temperature. |
