煤大分子结构的电子自旋共振谱表征

The Characterization of Coal Macromolecular Structure by ESR Spectroscopy

应用ESR技术对一变质系列煤的自由基特性进行了实验研究,探讨了煤中自由基的起源、性质和数量的变化,并将其与煤的大分子结构相关联。结果表明,煤自由基特性在煤化过程中的规律性较好。

The free radicals of coals in different ranks were characterized by ESR method. Their originproperties and variation of amount which are related to coal macromolecular structure arestudied. The results shown that there are some good rules for the characterization of freeradicals of coals in coalification.
