Previous publications indicate that the mechanical properties of metallurgical coke made from coal pr~odt1c4 in the Ostrava-KarvinB coal basin are significantly influenced by the coal mass properties-atomic ratio (H/O,,), vitrinite reflectance (% Rev) and inertinite content (y,; I). In the range of

Two Polish subbituminous coals, containing 76% and 82% C, were hydrogenated in a batch stirred autoclave at 400,430 and 46O"C, under 20 MPa hydrogen pressure and at contact times of 20, 60,90 and 120min, in the presence of a coal-derived recycle oil. No external catalyst was used. The filtered react
