摘要
采用13CNMR方法,研究了我国高煤级煤系列样品的碳结构及其演化特征,进而结合电子顺磁共振测试成果对演化的地球化学机理进行了探讨.研究表明:高煤级煤碳结构呈阶跃式和阶段性演化。
The carbon structure and its evolution of some Chinese high rank coals were studied using 13 C NMR, and their geochemical mechanism was then discussed in combination with the EPR responses of the samples. The results showed that the carbon structure of high rank coals develops in a jump pattern which might be controlled by making up function, a principal geochemical mechanism during the middle late stages of high rank coalification.
