| 摘 要： | 本文以阿尔伯塔次烟煤为研究对象,对煤样进行密度段划分,测定了个密度段的汞含量,用低温灰化仪对各密度段煤样进行低温灰化,对低温灰进行XRD(X-Ray Diffractometers)分析,研究其中矿物成分及含量.分析了该煤样中汞、矿物及其灰分的相关性,提出了汞赋存于阿尔伯塔次烟煤中一种特殊矿物-赵击石(Chaoite)中的可能性.

| Abstract: | An Alberta sub-bituminous coal was analyzed in the paper. The coal sample was separated into different density sections. The mercury concentration in each density fraction was determined. The Low temperature ash was analyzed by XRD to find the mineral components in each density fraction. By comparing the content of mercury, mineral and ash in each density fractions, the potential correlation between mercury and Chaoite in Alberta sub-bituminous coal was found. |
