不同成因天然沥青的结构组成特征研究

Study on Structure and Composition of Natural Bitumen in Different Genesis

利用液相色谱等仪器分析手段 ,较系统地研究了不同成因类型的天然沥青及模拟沥青样品 ,特别是其中的胶质、沥青质重组分 ,揭示了沥青结构组成中的成因信息。研究表明 ,不同成因的天然沥青具有各自特有的化学结构和组成 ,综合利用其结构组成特征能准确有效地判断天然沥青的成因类型 。

Natural bitumen and simulated bitumen samples in different genesis have been analyzed and studied systematically using liquid chromatograph and several other analytical instruments. Studies were focused on the characteristics of their resins and asphaltenes. And so, lots of genetic information in the structure and composition of natural bitumen has been revealed. As different types of bitumens possess their own special chemical structure and composition, the classification of natural bitumen using structure and composition can be used widely and effectively. This study is of great values in bitumen exploitation and application.
