摘要：

Five Indian coals of different ranks (C% similar to 73.6-92.8) have been demineralized by chemical method. Very slow scan X-ray scattering studies have been performed and coal structural parameters determined by a semi-quantitative method. The present study reveals that coal consists of a semi-crystalline turbostratic structure. Also, the high background of the diffraction profiles clearly shows that coal has amorphous carbon in its structure. d(002) value decreases and f(a) increases with increase in coal rank. There is a strong linear relationship between C% and volatile matter content with d(002) values of coal.
