煤中氮元素化学赋存形态及热迁徙规律的研究进展

RESEARCH PROGRESS OF CHEMICALLY INBORN FORM AND HOT MIGRATION REGULARITIES FOR NITROGEN ELEMENT IN COAL

煤中氮元素在煤燃烧过程中会转化为各种氮的氧化物,从而造成环境污染。针对煤中氮元素的化学赋存形态、煤热解过程中氮元素的迁徙规律以及煤燃烧过程中氮氧化物的释放规律进行综述,并对现有研究进行了总结。

During the combustion process of coal, the nitrogen element in coal may turn to various oxides of nitrogen, thereby, resulting in ambient pollution. A roundup directing against the chemically inborn form of nitrogen element in coal, the migrition regularity of nitrogen element in pyrolysis process of coal, as well as the releasing regularity of nitrogen oxides in combustion process of coal, has been carried out, and a summarization of research at present being made.
