Quantitative electron microscopy permits direct measurement ot organic sulfur in coal. Compared with the ASTM method, the electron microscopy technique has some advantages. It is direct and reliable, but the distinetive advantage is that it needs much less sample. It also allows determination of the spatial distribution of organic sulfur concentration on a scale of a few hundred angstroms. TEM has better resolution than SEM, though their accuracy and reliability in measurement of organic sulfur are comparable....

Quantitative electron microscopy permits direct measurement ot organic sulfur in coal. Compared with the ASTM method, the electron microscopy technique has some advantages. It is direct and reliable, but the distinetive advantage is that it needs much less sample. It also allows determination of the spatial distribution of organic sulfur concentration on a scale of a few hundred angstroms. TEM has better resolution than SEM, though their accuracy and reliability in measurement of organic sulfur are comparable. Our applications include measurement of average organic sulfur content of coal. This paper shows a systematic study of the organic sulfur concentration and its distribution in the immediate vicinity of pyrite in the coal.Experimental results show that: (1) the organic sulfur content of macerals does not increase in the vicinity of pyrite in the original coal, at least with in the range of 1μm, (2) the pyrite (FeS_2) in coal may change into pyrrhotite(Fe_(1-x)S)or magnetite (Fe_3O_4) during heating and that some inorganic sulfur may migrate into the coal matrix near the mineral particles. The range of the measurement of organic sulfur is 1-40μm from pyrite. The range of the heating temperature is 400-550℃.
