中文摘要	利用FTIR分析技术,对3种不同煤阶的我国电站典型动力用煤———神木烟煤、铜川贫煤和宜宾无烟煤的挥发份中氮的赋存形态进行了研究。为克服研究工作中的微氮现象,在研究过程中采用了16m光程的长程气池。研究结果显示,红外光线在16m长程气池构造作用下多次穿过挥发份,检测出含量微少的氮元素,成功地克服了微氮现象,取得了较好的研究结果;我国电站用煤的挥发分中氮的赋存形态有4种,分别为吡啶型氮化合物、吡咯型氮化合物、吡啶-N氧化物和腈类化合物。氮在煤与挥发分中赋存形态的差别主要是由于煤分子中的大分子量含氮结构在温度作用下发生分解所致。; Nitrogen functionalities of volatile of three different rank coals, namely TONGCHUAN lean coal, SHENMO bituminite and YIBIN anthracite, were studied by using Fourier transform infrared spectroscopy (FTIR) equipped with 16 m long path distance gas cell. The detection problem of low content of nitrogen in volatile was successfully solved because of the application of the long path distance gas cell. In the long path distance gas cell, the infrared penetrates the sample more times than in a normal gas cell. Results from the analysis of spectra obtained by FTIR show that there are four functionalities of nitrogen in volatile, including pyrrole-type nitrogen, pyrindine-type nitrogen, pyridine-N-oxide nitrogen, and nitrile nitrogen. Comparison of research results of nitrogen group between coal and volatile suggests that the difference in fate of nitrogen between volatile and coal results from the macromolecular nitrogen group of coal decomposition under the effect of temperature.; 国家重点基础研究发展规划项目(G1999022210)资助
