| 摘 要： | 用XRD和TG等方法对无烟粉煤制炭化型煤的微观结构进行研究.结果表明:与石墨相比,炭化型煤的d(002)较大,但Lc和La较小.炭化型煤中的微晶无规则地连接,具有乱层结构;无烟煤成型块炭化时没有流体状胶质体形成,无烟煤颗粒通过黏结剂与细粉形成的胶料把它们黏结在一起,黏结剂与无烟煤颗粒表面有明显的作用界面;炭化型煤微晶结构与气孔结构共同决定炭化型煤的反应性.

| Abstract: | The microcrystal structure of carbonated briquette made from Changzhi anthracite powder was studied by use of X-ary diffraction and TG. The results have shown that the microcrystal parameters d(200) is larger,but Lc and La are smaller than that of graphite. There were micro-crystals in the carbonizated briquette made from Changzhi anthracite powder. The arrangement of the micro-crystals in the carbonizated briquette was quite irregular,so that the structure was called irregular structure. When a briquette w... |
