中国煤中硫的赋存特征及脱硫

随酸雨而提出的控制ＳＯ＿２污染是洁净煤技术的主题。煤是中国的能源支柱，而燃煤造成的硫污染尤为突出。从空间、时间上讨论了中国煤中硫的分布特征，也从微观上说明了煤中有机硫的分布。统计数据表明：煤中有机硫污染的贡量与日俱增，脱除煤中有机硫是一项迫切任务。介绍了多种脱除硫的方法。开展直接测定煤中有机硫含量和制定有机硫类型的研究，也是一项十分迫切需要解决的课题。

CHARACTERISTICS AND DISTRIBUTION OF SULFUR IN CHINESE COALA AND DESULFURIZATION

Reducing pollution of SO_2 is a main subject in the field of Clean Coal Technology(CCT). Coal is the mainstay of energy in China in the areas of re-sources,development and consumption. Emission of sulfur dioxide from coal com- bustion makes up more than 90%of the total emission in China .Large quantities of SO_2 are emitted to atmosphere and caused the pH value of acid rain is about 3. 0 in some areas,Getting a clear understanding about the distribution of sulfur in Chinese coals from the point of view of geographical areas and geological periods and study-ing on the characteristics of sulfur forms are important subjects, The desulfu-riza- tion of coal,especially to remove the organic sulfur in coal,is an urgent task in coal utilization. Setting practical methods to determine the content and forms of organic sulfur in coal directly are occupying an important place in desulfurization of coal.
