| 摘 要： | 采用Ｘ衍射（ＸＲＤ）方法研究了各种烟煤焦炭在１５００℃下的微晶结构特点并计算了结构参数，表明低变质程度烟煤焦炭的微晶化程度差，Ｃ含量低，活性好；中高变质程度烟煤焦炭的微晶化程度好，Ｃ含量高，活性差。

| Abstract: | This paper studies the crystallite structure characteristics of high temperature cokes of coals at 1 500 and calculates their structure coefficient by the methoed of XRD.It shows that the cokes of middle and high rank coal have the better crystallizability and higher component of C than that of the coke of low rank coal,but they have lower activity than that of the coke of low rank coal. |
