Artificial super coal (ASC) was named from its high coking abilities coming out through hydrogenative thermal processing of low rank coals at a moderate temperature and a mild pressure using hydrogenated heavy solvent. ASCs were prepared from a Chinese subbituminous coal with a high inertinite maceral composition, and from an Indonesian subbituminous coal with a poor inertinite maceral composition. Morphological changes of ASCs derived from the low rank coals, and cokes derived from the ASCs were studied under an optical microscope. ASCs were composed of hydrogenated pitch matrix and fine particles densely dispersed in the matrix. In the cokes derived from ASCs, optically anisotropic textures were recognized under the microscope.
