中国煤中硫氮的赋存状态研究

煤中的硫、氮在煤利用转化过程中的释放对环境和生物健康影响巨大。笔者从煤中硫、氮的分布、结构,同位素研究等几方面对中国煤中硫、氮的赋存状态研究进行了总结,并提出了今后的研究方向和热点问题。 China is the largest coal producer and consumer in the world and coal is the most important energy in China. This paper has systematically reviewed the date in literature on the contents and distributions and isotopes of sulfur and nitrogen in Chinese coals,and proposed some geochemical study on sulfur and nitrogen
