On the Molecular-Level Interactions Between Pocahontas No. 3 Coal and Pyridine
Chemistry and Biochemistry
Mathematics and Natural Sciences
Pocahontas No. 3 coal is a low volatile bituminous coal containing, on the average, poly-cyclic aromatic (PCA) units of C20 in the x−y plane. The average interlayer distance between these PCA layers is 3.53 ± 0.02 Å; so the z-dimension of the average short-range structural unit of POC, which contains ca. 5 layers of PCA units stacked in an approximately parallel manner, is ca.14 Å. The high aromaticity of POC suggests the possibility of extensive interlayer π−π interactions, but its very low oxygen atom/carbon atom ratio indicates that POC has few oxygen sites available for hydrogen-bonding.
