| 摘 要： | 为了解我国煤中氮的含量水平及其分布特征,在全国主要产煤的26个省、市、区,根据各煤田的地质储量、成煤时期和煤变质程度,兼顾各矿区的煤炭产量,采集306个煤样,测定了全部样品的氮含量,并对各成煤时代、各聚煤区、各省市区的煤氮含量进行了统计分析。研究表明:煤中氮主要以有机形态赋存;氮含量与煤变质程度间有微弱的正相关关系;全国煤的氮含量近似服从正态分布,90%的样品含氮范围为0.52%～1.41%,宜用算术平均值0.98%作为全国平均煤氮含量。

| Abstract: | A nationwide sampling program was designed according to the resource distribution and coal-forming periods as well as coal rank and yield of coal in China,and 306 coal samples were collected from 26 provinces,municipalities and autonomous regions.Nitrogen in coal was determined.Nitrogen in coals is principally of organic nature.A weak positive correlation between coal rank and nitrogen content is inferred in the study.The distribution of nitrogen in coals of each geological age,coal-cumulating area and province was studied.The contents of nitrogen in Chinese coals show approximately a normal distribution,and 90% of the values range from 0.52% to 1.41%,the average nitrogen content in Chinese coal is designated as the arithmetic mean,0.98%. |
