摘要
研究了煤中氯在热解过程中的释放特性与煤变质程度的关系,研究结果表明,煤中氯的含量主要受地质条件和煤的形成过程的水文等条件(如水中氯化物的浓度)的影响,而其热解时的释放特性则与煤的变质程度有密切的关系。采用热力学方法研究发现,煤中氯释放的能垒(或近似认为是活化能)与煤的挥发分含量有定量关系。
The relativity between the rank of coal and release characteristic of chlorine in the process of pyrolysis was studied. The result indicates that the content of chlorine in coal is influenced by geological and hydrological factors in the process of coal formation. And there is a near relativity between the release characteristic of chlorine in pyrolysis and the rank of coal. It is considered that the relativity of activity energy and volatile matter of coal is quantificational.
