摘要

采用热分析仪、滴管炉等研究了Fe_2O_3对煤焦热解过程的催化作用,借助XRD分析了Fe_2O_3在不同反应温度下的转变产物。结果表明,添加Fe_2O_3后煤焦热解吸热量明显下降,生成烟气中CO、CO_2含量显著上升;Fe_2O_3在1000℃和1100℃时的主要转化产物分别为Fe_3O_4和FeO,在1200℃时转变为Fe_3O_4、FeO和Fe。
        By means of thermal analyzer and drop-tube furnace,the catalysis of Fe_2O_3 for pyrolysis of coal char was investigated,and the transformed products of Fe_2O_3 under different reaction temperatures were characterized by XRD.The results show that after Fe_2O_3 is added,the pyrolysis heat absorption of coal char decreases and the contents of CO and CO_2 in flue gas increase markedly.Fe_2O_3 is transformed mainly to Fe_3O_4 at 1000℃,FeO at 1100℃,Fe_3O_4,FeO and Fe at 1200℃,respectively.
