Abstract: The high-angle scattering intensities from coals can be interpreted with a modle of a buckled sheet of a macromolecule in coal. Those which take part in the (hk) 2-dimensional interferred scattering, i. e. aromatic lamellae, only make up of a part of a macromolecule in coal. Amacromolecule in coal consists of a few aromatic layers through the cross-linking bonds of amorphous materials, such as, aliphatic materials, hydro-aromatic groups, five-ring structure etc.. With the increase of the rank of coals, the dimension of aromatic layers increases, and amorphous materials decrease.

Key words: Coal, Coal structure, Macromolecule in coal, X-ray scattering
