Abstract
The report describes an automated scanning electron microprobe method of analyzing sulfur forms and mineral matter in coal. The microprobe is used to measure the spatial distribution of a number of elements (including Fe, S, Si, Al, Ca, and K) on a scale where individual grains can be observed. These data are then analyzed to extract the following information: organic sulfur concentration; mineral sulfur concentration; total sulfur concentration; major mineral concentrations, including Al2O3, SiO2, K2O, and CaCO3; and stoichiometry of iron sulfide, FeSx. The procedure is fully automated: all of the above information is obtained on a 200 mg coal sample in less than 15 minutes. Sulfur forms and total sulfur were reproducible to within 0.1 wt%. In addition, estimates of the pyrite particle size for two coals were obtained from the spatial distribution of the Fe and S data, and these estimates are compared with the results of a washability study. A commercial elemental analyzer, evaluated for use in determining nitrogen in coal, gave results that were reproducible and accurate to within 3%.
