摘要
以中国煤种资源数据库为基础，系统地考查了中国煤中硫分的分布状况，发现低阶煤的硫分普遍较低，高阶煤的硫分相对较高，不同地区煤中硫分也有很大差别，以东北地区最低，其中尤以黑龙江省的最低，中南地区平均硫分最高；在我国高硫煤中硫的组分除少数小型矿区以有机硫为主外，其他绝大多数矿区均以硫铁矿硫为主，表明中国的高硫煤通过洗选方法可脱去大部硫分。
The sulfur distribution in Chinese coal are investigated based on the China Coal Resources Databank. Sulfur content in low rank coal is lower than the high rank coal and sulfur content in coal has a world of difference at different areas in China. The lowest sulfur content coal resource is located at the north-east of China, especially in the Heilongjiang Province.The highest sulfur coal is located at the Central-south of China. The sulfur form is mainly pyretic sulfur in the most of high sulfur coal, except that several small mine areas which the form is mainly organic sulfur. It is shown that, most of high sulfur coal can be removed by coal preparation.
