煤在热解过程中氯的释放特性研究和煤中氯的吸附模型的建立

通过不同煤样的热解实验,研究了在还原环境中加热时煤中氯的的释放特性,并根据实验数据分析影响氯释放的因素,从而建立了煤中氯赋存的吸附模型,计算出不同煤样的吸附热。计算结果表明,吸附热与煤的变质程度有关,特别是与煤的挥发分成线性负相关。 The chlorine emission characteristics during coal heating in reductive atmosphere were studied through different coal samples pyrolysis and analysis the factors influencing chlorine emission.The absorption model of chlorine occurrence in coal was established and the absorption energy of different coal samples was worked out.The results indicate that absorption energy is related with coal rank,especially with volatile matter form a linear relation
