“…Ergun [1,2] carried out a X-ray diffraction quantitative analysis on coal and its distilled product. Wertz's group [3][4][5][6][7][8] used a radial distribution function (RDF) from Fourier transforming of molecular catering, to examine the molecular-level structure of coal. Schoening [9,10] had also carried out similar work.…”

Applying X-ray diffraction, an analysis of crystallite structure on the coal samples from Hami, including raw coal and coals heated respectively at 200°C, 250°C and 300°C, was carried out. The results show: The intensity of the 002 diffraction peak increases, the γ diffraction peak of the coals decreases, the 100 diffraction peak appears and its intensity increases, the size of the crystallite, the stacking height of the aromatic layer and the condensation degree of the aromatic rings increase, and the proportion of the non-crystallite decreases in coal samples, with the temperature increasing at below 300°C.
