Abstract

The thermolysis of Mongolian coals of different ranks was studied using thermal analysis (TG/DTG). The stepwise decomposition under conditions of programmed heating to 1000°C in an atmosphere of argon was found. The kinetic parameters of pyrolysis were determined based on thermogravimetric analysis with the use of model-fitting (Coats–Redfern) and model-free (Ozawa–Flynn–Wall) calculation methods. Changes in the activation energy with the degree of decomposition of the organic matter of coals of different ranks were established. A kinetic compensation effect was revealed, which was, probably due to the multicomponent composition of coals.

蒙古各种煤逐步热分解的动力学研究

摘要

利用热分析（TG / DTG）研究了不同等级的蒙古煤的热解。发现在氩气气氛中在程序升温至1000℃的条件下的逐步分解。热解的动力学参数是在热重分析的基础上使用模型拟合（Coats–Redfern）和无模型（Ozawa–Flynn–Wall）计算方法确定的。建立了不同等级煤的活化能随有机物分解程度的变化。揭示了动力学补偿作用，这可能归因于煤的多组分组成。
