1) four fractions of asphalt
沥青四组分
1.
The non-isothermal process of four fractions of asphalt and several base asphalt is studied by TGA,and the results show that the sharp decomposition temperature of saturates,aromatic,resins and asphaltenes is 300℃,412℃,438℃,472℃ respectively;the decomposition temperature of asphalt with more saturates content is lower.
采用热失重分析仪(TGA)对沥青四组分及几种基质沥青进行非等温热失重分析,研究表明,饱和分、芳香分、胶质、沥青质开始迅速分解时的温度分别为300℃,412℃,438℃,472℃;含饱和分较多的沥青分解温度较低。
2) asphalt component
沥青组分
1.
GPC methodology was utilized to analyze the result of present asphalt component, which showed that two different components exit in one asphalt component.
以沥青凝胶渗透色谱(GPC)方法对目前划分沥青组分结果的分析为基础,指出了沥青同一组分结果中存在2种不同的组分,不能很好地把性质相似的化合物分到1个组分中。
3) asphaltene fraction
沥青烯组分
1.
Study on the molecular structure of asphaltene fraction from the Shenhua coal direct liquefaction residue;
