低煤化度煤经低温热解后各基团变化的研究

THE STUDY OF GROUPS VARIATION OF LOW RANK COAL DURING LOW TEMPERATURE PYROLYSIS BY FTIR SPECTROGRAPHY

对兖州、大同煤及其低温热解后的试样进行FT-IR测试，确定各吸收带的归宿。采用内标法测定了各基团的相对含量，考察了它们随热解温度的变化。

Yanzhou and Datong coal, after pyrolysis at low temperature,are characterized by FT-IR speetroscopy. The absorption spectrum is interpretated-Using internal standard method the groups' relative content are determined,and the variation of the groups with the pyrolysis temperature are investigated.
